Cruise ships require a lot of power to sail and operate. The cruise ship engine room is both mysterious and fascinating because it’s hidden from passengers.

Passenger ships have come a long way from sails and steam engines. Modern cruise ships use diesel-electric engines, while newer cruise ships are moving towards more environmentally friendly solutions like liquified natural gas.

Here’s everything you need to know about a cruise ship’s engine room.

Where is the Cruise Ship Engine Room?

The engine rooms on cruise ships are located on the lower decks, between the midship and the aft. The engines aren’t quite at the back of the vessel but closer to midship.

There are several reasons for keeping the cruise ship engine room away from passenger areas.

• Stability : Placing the engines and heavy equipment below sea level helps keep the ship stable and prevents cruise ships from tipping over .
• Noise : Engine rooms are extremely noisy. Naval engineers compensate by incorporating sound reduction features and noise dampeners. However, the sound and vibration wouldn’t be pleasant for cruise ship passengers.
• Security : The engine room spaces are in crew-only areas for safety and security purposes.

Most of the heavy machinery on a cruise ship is located on the lower decks, just above the keel. The positioning of the engine room, other machines, and technical equipment give the massive vessels a lower center of gravity.

Although you might envision the engine room as a massive open room running the ship’s length, the lower decks are divided into several water-tight compartments. One compartment may house the cruise ship water fresh water systems , another for the main engines, and another for the air conditioning.

The division of the engine room into separate compartments is for safety. Dividing the engine room into different containers makes it easier for the ship to contain the damage if there’s a fire or leak in the hull.

Cruise ship fuel tanks are also on the lower decks, but they are kept separate from the main engines.

Crew members can monitor the ship’s systems from the engine control room. From the operation control center, crew members monitor the ship’s systems and act as a central area for maintaining the technical equipment on the cruise ship.

Every piece of equipment can be monitored from the engine control room to ensure the cruise ship runs smoothly.

The room is monitored 24/7 by watchkeeping teams. Each crew member is assigned specific machinery. For example, one person may be responsible for the freshwater generators and water pumps and another for the fuel oil systems.

How Big is a Cruise Ship Engine?

A cruise ship engine room spans several decks and holds the ship’s engines, fuel tanks, water systems, generators, control room, engine workshop, air conditioning, and other essential navigation systems.

Modern diesel-powered cruise ships have between four to six medium-speed (500 revolutions per minute) engines . Each engine can generate upwards of 25,000 horsepower or nearly 18.5 megawatts.

The engines on a cruise ship can be up to 45 feet long, 27 feet high, and weigh up to 275 tons .

These massive engines can propel cruise ships at an average speed of 18-22 knots .

Cruise Ship Engine Technology

Cruise ship engine technology has evolved from wind and sails to newer liquified natural gas technology.

We’ll cover some of the most popular technologies used by cruise ships.

Steam Engines

When the cruise industry began in the mid-1800s, vessels were propelled by steam engines.

Steam engines had boilers that used wood for fuel. Later steam engines used coal.

The boiler produced steam which created pressure in a pressurized system. The pressure moved pistons which drove the propeller shaft.

The Titanic was powered by two huge triple-expansion steam engines and a small propeller. ( Source )

Diesel Engine s

Diesel engines propel most modern ships. Cruise ships may have four to six medium-speed (500 rpm) engines producing 8-10MW each .

Diesel engines work on the same concept as steam engines. Rather than steam, the ignition of diesel fuel pushes the pistons up and down, turning the crankshaft attached to the propeller shaft.

Many of today’s diesel-engine cruise ships also employ a shaft generator to generate electricity for shipboard services, like lighting.

A shaft generator converts the circular motion of the propeller shaft into electricity. However, shaft generators only operate when the ship is moving. And can’t generate electricity while docked in port.

Diesel-Electric Cruise Ship Engines

Almost all new diesel-powered cruise ships use diesel-electric engines.

The engines work the same as a traditional diesel engine, but rather than connecting to the propeller shaft – diesel-electric engines connect directly to large generators .

A diesel-electric engine has one job, generating electricity.

The electricity produced by the engine is used to power the ship’s propellers.

These engines provide greater efficiency than traditional diesel engines.

While connected to a generator, the engines can run at their most efficient settings regardless of the travel speed . Whether the ship is sailing at 10 or 20 knots, the engines can operate a peak efficiency.

Diesel-electric engines are popular because of their ease of control, low noise, minimal vibration, and relatively compact size compared to other forms of propulsion.

Marine vessels that run on diesel power must carry exhaust-treatment systems and catalytic-reduction equipment to reduce the environmental impact of the ship.

Gas-Turbine Power System

Royal Caribbean Group was the first company to experiment with gas-turbine systems.

Compared to diesel engines, gas turbines offer several advantages, including:

• Lower environmental impact.
• More reliable.
• Take up less space.
• Gas engines require a smaller maintenance crew and less inventory.

The heat generated from the engine is recovered and used to produce electricity for other onboard systems, such as air conditioning and water heating.

Despite their advantages, gas propulsion is not widely used in the cruise industry. Gas-powered ships are faster, but most cruise ships don’t travel faster than 22-25 knots .

Diesel engines have greater fuel efficiency at slower speeds , and the high gas price compared to diesel makes them more costly to operate.

LNG Powered Ships

Many new cruise ships are propelled by liquified natural gas (LNG).

LNG is the cleanest fossil fuel currently produced. According to Cruise Critic , LNG-powered cruise ships can “reportedly reduce sulfur emissions by as much as 99 percent and nitrogen oxide emissions by up to 85 percent.” LNG can reduce carbon emissions by up to 20 percent .

The special engines of LNG-powered cruise ships use natural gas cooled to approximately -260°F. Once cooled, the liquid form of natural gas is about 600 times denser than natural gas , making it easier to transport.

Carnival Cruise Line announced the first LNG-powered vessels in 2015, using a “dual fuel” design. The ships can burn both liquified natural gas and marine fuel, reducing the required fuel storage space.

AIDAprima became the world’s first LNG-powered cruise ship on her debut in 2016.

Natural gas is purer, cleaner, more efficient, and cheaper than other fossil fuels . But it’s a relatively new technology, and not all ports have the facilities for refueling LNG-powered ships.

Because natural gas burns cleaner than other fossil fuels, the engines require less maintenance. But LNG has a lower fuel density than diesel, so LNG vessels need fuel tanks that are twice the size.

Emergency Generators

Every cruise ship has an emergency generator to maintain vital electrical power in case of engine failure.

The emergency generators are located away from the main engine room, usually on a higher deck. Their location isolates them from catastrophic damage in the engine room (for example, a fire).

The generators can operate critical navigation systems, emergency lights, and other vital equipment. But emergency generators can’t power the ship .

Larger ships may have multiple emergency generators. But due to the size constraints, they can’t produce the same power as the main engines and cannot propel the ship.

What happens if the generator fails?

Cruise ships have several redundant systems to ensure the safety and security of passengers. If the generators fail to work during an emergency, cruise ships have an emergency battery backup to power the most critical systems for up to 24 hours .

Shore-to-Ship Power Supply

Despite innovations in engine technology, cruise ships produce a lot of pollution.

To further reduce ships’ environmental impact, many cruise ships can connect to the cruise port’s power grid , known as “shore-to-ship power” or “cold ironing.”

In the past, cruise ships kept their engines running while docked to generate electricity for shipwide services.

But most of the energy produced by the ship’s engines goes towards powering the propellers, and running the engines while docked created massive energy waste.

Some cruise ships used smaller generators to power the hotel and amusement functions. The smaller generators allow cruise ships to shut off the main engines in port, reducing pollution.

Modern cruise ships are equipped with systems to “plug in” to the local power grid. Even some older cruise ships are being retrofitted to allow for shore-to-ship power.

Not all cruise ports have facilities to enable shore-to-ship energy. But many larger cruise ports have dockside electrical hookups that allow cruise ships to shut off their engines and run on the city’s electrical grid. The technology reduces harmful emissions by up to 95% while ships are docked .

Considering how much time cruise ships spend docked at port, it significantly reduces sulfur and carbon emissions.

How Loud is the Engine Room of a Cruise Ship?

A cruise ship engine room is incredibly noisy, exceeding 173 decibels . At this noise level, the noise in an engine room can cause immediate damage to your hearing without proper ear protection.

For reference, a gunshot is 130 decibels.

Engine rooms have insulation and sound-reducing technology, so it’s not as noisy. To prevent hearing damage, crew members must wear hearing protection when entering the multi-story engine room.

But guests don’t have to be concerned about the noise.

Thanks to the insulation and sound dampening, you’ll only hear a slight “purr” if you’re near the engine room.

You may feel the engine’s vibration if your cabin is on the lower decks, near the aft . On most ships, the noise isn’t enough to cause any annoyance or trouble sleeping.

But if you’re a light sleeper, accommodations near the engine room are among the worst cabins on a cruise ship .

Where are the Fuel Tanks?

The fuel tanks are located below the passenger decks , near the engine room. The fuel is stored in double bottom tanks.

How Much Fuel Can a Cruise Ship Hold?

A large cruise ship of 1,100 feet in length can hold between 1 to 2 million gallons of fuel .

It’s enough to power the cruise ship for up to two weeks of sailing without refueling.

Are There Cabins Near the Engine Room?

Newer cruise ships have a large gap between the cruise ship engine room and passenger cabins to minimize noise and vibrations.

However, you may still find cabins reasonably close to the engine room.

If you book a cabin near the engine room, you can expect to hear some noise and feel the vibrations caused by the engines . However, cruise ships use sound-dampening technology and insulation to minimize noise pollution.

The engines are typically cheaper because most passengers avoid booking cabins next to the engine room.

Cabins near the cruise ship engine room aren’t noisy enough to cause annoyance or sleeping issues.

If anything, the vibrations caused by the engines are more likely to cause annoyance over the sound of the engine .

How Much Fuel Do Cruise Ships Use?

It takes a lot of fuel to power a cruise ship.

The average cruise ship uses around 18.3 gallons of fuel per minute or 1100 gallons per hour . ( Source )

How Cruise Ships Work (Part 3): The Bridge and the Engine Room

It’s like back in the days when we were little children. Grandpaw’s almost mystical tool shed was strictly off limits, but we were just dying to have a peek, weren’t we? Now that we are all grown up, Grandpaw’s gadgets are old news, but there is still a place or two on a cruise ship that remains like a pie in the sky for all of us obsessed by ships.

It’s the heart of the matter, it’s where it all happens, it’s the real deal. And if you are anything like me, you would gladly give away a day at the spa, a dessert buffet and even two, or the latest Marvel flick in the movie theater, just to spend a precious hour down in the noisy engine room of your favorite cruise ship. But life being proverbially unfair, modern cruise lines rarely allow their passengers to enter the bridge or the engine rooms of their ships, unless the visit is part of a specially organized guided tour. Some cruise ships have a window from which passengers can observe what’s going on in the bridge, but only if they promise not to disturb the officers. Which is really hard, when you badly want to touch everything…

So until the next time someone lets me out of sight and I make my umptieth attempt at trespassing to the engine room, let’s have a quick virtual tour of a cruise ship’s most forbidden and exciting parts.

The bridge is the brain of the ship. It is from there that the captain and his officers command and maneuver the ship, keep watch for other vessels or potential hazards, and navigate through the oceans. 

For twenty-four hours each day, the bridge is occupied by two Deck Officers and two Able Seamen, traditionally in four-hour shifts. The main job of the Officer of the Watch is to monitor the ship’s systems and surroundings, and to ensure that everything is running safely and smoothly. During extreme weather, docking, or other special cases, the Captain of the ship is also present on the bridge to guide the deck officers.

The term “bridge” comes from the time of the paddle steamers, where a bridge was built above the two paddle houses that used to hold the paddle wheels. This way the skipper could observe both wheels, while moving freely between the two and giving out commands. On today’s cruise ships, the bridge is usually on the upper deck in the forward part of the ship and extends over the sides of the superstructure, allowing deck officers a view to the sides of the ship as well as down to the waterline. The side extensions are called bridge wings and often have a glass flooring for better visibility.

The bridge houses a number of important nautical devices and information systems for command and navigation of the ship.

Satellite Navigation

The signals emitted by special navigation satellites are picked up by the cruise ship through a special antenna. On board, a computer converts these signals into the exact position of the ship at a given time. On large ships, the position indicator is constantly recorded in a so-called electronic nautical chart.

Satellites also enable automatic positioning systems on modern cruise ships. The positioning system is controlled from the bridge and it uses GPS to ensure that the ship stays at a defined location. When the captain defines a position where the ship needs to remain for a while without anchoring, the system automatically maintains the ship in position by using the bow and stern thrusters.

Modern cruise ships carry a gyro compass and a magnetic compass. The gyro compass consists of a fast-rotating disk, usually positioned in a gimbal. It is a non-magnetic compass oriented parallel to the axis of rotation of the earth and thus indicates the north-south direction.

The gyro compass is more accurate and reliable than the magnetic compass and is therefore the primary reference point for steering the ship. The magnetic compass on board is more prone to inaccuracies and it serves only as back-up.

The word radar stands for Radio Detection And Ranging. Radars are devices that allow us to locate distant objects from a given location, regardless of visibility and weather conditions. The radar emits electromagnetic waves to an object, then receives back the reflected echoes from that object, and interprets them based on distances and angles. These interpretations enable us to determine where an object lies, and in some cases even what its contours look like. In the shipping industry, radars are used for monitoring traffic in ports and coastal regions, for collision protection, for collecting weather data, and for navigation.

Speed logs are devices that measure the speed of the ship. There are two main types of speed logs: Doppler logs and electromagnetic logs.

The Doppler logs send out underwater sound signals. When the sound wave reaches the sea floor, it gets reflected and then returns to the receiver of the log. Due to the movement of the ship relative to the seabed, a Doppler effect occurs and is evaluated by the device. As long as the sound waves can reach the bottom of the sea and return to the receiver, the Doppler log measures the distance travelled over ground. However, if it is no longer possible to use the seabed as a reference, the device uses particles suspended in the water, such as plankton and minerals, to measure travel through the water.  

The electromagnetic logs create an electromagnetic field in the water around the ship, with the aid of a small alternating current and a transducer. A voltage proportional to the speed of the ship is generated in the water and is picked up by special sensors, which then transfer the information to an electronic device for interpretation. From the electronic device, the speed is then transmitted onto the displays in the bridge.

Echo Sounder

Cruise ships also have an echo sounder, a device used for the electro-acoustic measurement of water depths (sounding). The depth is determined by measuring the time between the emission of a sound impulse (water sound) and the arrival of the sound waves reflected from the bottom of the sea. The main purpose of echo sounders in cruise ships is safe navigation through waters.

Electronic Chart Display and Information System

The Electronic Chart Display and Information System (ECDIS) is a console, built into the bridge of modern cruise ships, which incorporates the main engine safety system, fire control system, monitoring and control system, power management system, propulsion control system and navigation and maneuvering system. The ECDIS allows for navigation of the ship without the need of traditional paper charts. Navigation can be done manually, automatically, or through the Navigation and Command System (NACOS).

The NACOS is the main software used to coordinate all factors that need to be taken into consideration, in order to navigate and maneuver the ship safely. The console is composed of a number of displays showing information from the radars and compasses, data about the course of the ship and planned maneuvers, the current status of the pitch of the thrusters, the speed of the ship, and anything else concerning the steering of the ship. An intelligent autopilot tracks changes in the behavior of the ship through navigational sensors. If the ship drifts off its course due to strong winds, for example, the system automatically responds to correct the change by sending signals straight to the engine room. Once the signal is received by the engines, the rudder or thrusters of the ship are activated and move to the position given by the system. The displays on the bridge show both the angle of the rudder or thrusters, as well as the rate and the radius of the maneuver in progress.

The Engine Room

The engine room is the heart of a cruise ship. It is here that pistons hammer and crankshafts turn to propel the ship forward. It is the loud and oily place where the Chief Engineer and his team work around the clock to ensure that everything is running smoothly. It is the engine room of the ship that allows for the luxuries of air-conditioning, electricity, and plumbing on board cruise ships.

In future articles we will have the chance to explore the contents of the engine room in all the excruciating detail that they deserve, so to all the techies out there – I’ve got you covered. Just stay tuned.

Most larger ships have more than one engine room to house their machinery. The arrangement of the engine room can vary depending on the type, design, and size of the ship. For stability reasons, the engine machinery is typically placed as low as possible in the ship’s bowels and often takes up several decks in height. The machine rooms are split into watertight compartments, each housing different machinery.

Today’s cruise ships operate on diesel or diesel-electric engines. Their operating principle does not differ much from the old days of coal steamers, except for the medium used to generate power. While back in the day ocean liners used steam to move the engine’s pistons, modern cruise ships use diesel fuel. Today’s diesel engines are composed of the engine unit itself, gearboxes, shafts and generators. Some ships also have shaft generators which create electricity from the turning movement of the propeller shaft. The electricity is then used in the cabins, on deck and in the kitchens.

The latest generation of cruise ships are equipped with diesel electric engines. Instead of the more traditional engine-shaft-propeller arrangement, in this case the engines are connected to generators to create electricity. The generators power electric motors, and the electric motors move the propellers.

Aside from the engines and generators, the machinery that occupies the engine rooms includes pumps and heat exchangers for engine cooling, stabilizer fins and their motors, as well as the ship’s bow thruster system.

Since all of the equipment in the engine room is highly dependent on electricity, modern cruise ships also have back-up generators, usually located outside the main engine room, to protect them in case of fire. While these generators cannot produce enough power to keep the ship moving, they produce enough to keep some of the vital functions of the ship running, such as powering the emergency lights and the communication and navigation systems. In case the back-up generators fail, cruise ships are also equipped with a back-up battery that allows some of these functions to continue running for short periods of time. 

All the machinery in the engine rooms is monitored in the Engine Control Room (ECR). The ECR is a room full of screens, lights, alarms, and switches from where the current operational status of every piece of equipment can be checked.

The main switchboard of the ECR is used to distribute the generated electricity to where it is needed on board. The ERC is also where the engineering team comes together to discuss and plan the safe running of the engine rooms, to take decisions in emergency situations, to consult the technical manuals and drawings of the ship, to restart certain pieces of machinery if necessary, and to maintain communication with the bridge. Communication between the ECR and the bridge is crucial for the safe operation of the ship, especially during docking, moving through shallow waters, maneuvering, and changes in the course or speed of the ship.

This concludes our three-part overview of how a cruise ship functions. Now that we have covered the basics, in future articles we can explore all the specifics to our hearts’ content. As always, don’t hesitate to leave your constructive comments below and feel free to suggest topics you want to know more about – chances are I want to know more about them too!

All Access Ship Tour – Behind The Scenes Of A Cruise Ship

The All Access Ship Tour is a cruise ship tour that Royal Caribbean offers.  Virtually unheard of and unadvertised, most do not know this is an option! If you are naturally curious like me, you probably want to explore restricted areas. Here’s your chance. Explore the behind-the-scenes operations of cruise ships and discover how it all works.

Learn how the food is prepared and where the ingredients are stored.  Travel through the underbelly of the cruise and see the crew corridors, the Engine Control Room, the Bridge, the ship’s navigational center, and even behind the theater curtain!

This post may contain affiliate links. Please read our  disclosure and privacy policy  for more information.

I knew that these tours existed; I’ve cruised many times. However, I did not know the names or how to book, and I never really researched it until now! I recently cruised on Oasis of the Seas , where I first heard about this from another guest. Sadly, the tour was unavailable for us because cruising had just started post- COVID . Naturally, when I booked Wonder of the Seas to Bermuda , it was the first activity I booked.

FYI – The All Access Ship Tour is considered an “Excursion” and the listing lacks a full description of what it is.

All Access Ship Tour Includes:

• Main Dining Room
• Main Galley
• Provision Area

Environmental Services

• Engine Control Room
• Laundry Facilities
• Crew Corridor is I-95 – the long corridor in the crew’s area, named after the longest highway on the U.S. east coast.

This type of tour may not be available on cruises and is not always available on Royal Caribbean Cruises – it depends on the route and number of nights. Most cruise lines offer a similar type of tour, but they are all called something different.

The “All Access Ship Tour” of the Wonder Of The Seas is almost three and a half hours long. The experience was great, and we could see many areas of the ship that are usually off-limits to cruise ship passengers.

The galley is a kitchen on these impressive resort-like cruise liners. It’s more like a football field of kitchens! This will be your first stop on the All Access Ship Tour.

I’ve always been fascinated by how cruise ships handle food – especially food on board. The feat is almost astounding in light of the daily meals they prepare on a boat with over 3,000 guests and over 1,000 crew members. Chefs and kitchen staff on cruise ships deserve a lot of respect, no doubt about it.

You get to see where and how all the dishes are made. A senior kitchen staff member will explain how his kitchens stay efficient, safe, and clean.

The staffing efficiency is unparalleled in a kitchen. They are just as well-oiled a machine as the engine! All I can say is wow! It takes some coordination and then some. You could get lost in here, never mind carrying out multiple orders.

Food Storage

The Wonder of the Seas storage section stores all that food for the voyage. The refrigerated section alone is the size of a New York apartment!  The ship’s crew keeps everything fresh and ready for consumption here.

Crew Corridor – The I-95

This is another place where you could easily get lost. There are many doors, staircases, and crew members maneuvering behind the scenes of a cruise ship. You cannot photograph the crew areas or the confidential information on the walls. Once you start walking the I-95, you can not take photographs.

Cruises get a terrible rap for omissions and other environmental concerns. I was impressed with how Royal Caribbean approaches recycling. Everything from broken plates to cans is recycled, and it’s all compressed on the ship. The incinerators burn non-recyclables, and they are huge.

The ship’s environmental services officer knows more about maintaining and minimizing the ecological impact than most.  Our guide explained all the systems and protocols to ensure the ship maintains a low environmental impact. In addition to “scrubbers” that remove pollution from the smokestacks, the boat also uses recycled water and other materials, so it’s good to know it doesn’t harm the oceans.

Where Does the Poo Go?

I know you want to know. Everyone is curious! It gets explained before you can even ask.

The water is run through multiple filtration systems before it is returned to the ocean. This is the short answer to what happens to the poo flushed down the toilet.

The Engine Control Room

This is where any cruise fanatic, engineer, or person interested in nautical technology will have an orgasm. It’s also where most of the questions get asked. 

Prepare for a body scan to enter here. The security officers do not play. Not only will they scan you, but they will be inside with you, watching your every move.

Often called the “brain” of the ship – the engine control room where all systems are monitored. And, in the control room, they can override everything on the entire ship. A large cruise ship like the Wonder of the Seas relies on its engine control room as a nerve center. These include engine and propulsion systems, cooling systems, and environmental controls.

Ready for some more poo? Guess what? The engineers can see when we are using the bathroom! They cannot see you “using” it; they see the influx in the water flow. And, yes – this came up in the engine room.

The crew actively monitors every critical system aboard the ship. This room is continuously operated by someone who ensures the boat runs smoothly. In the middle of the room is a large table showing a schematic of the ship’s decks.

Most guests don’t get to see all the decks of a boat or behind the scenes of a cruise ship. I found it interesting to see this highly guarded zone below the water level.

The Laundromat

I don’t think the laundromat fits the bill. It is a laundromat but – holly molly. There are industrial bus -sized machines in here that press bedding! I can’t even begin to phantom the technology used to bring this together. Thinking about it makes my head hurt. Here is like being in the heart of the boat and you know you are behind the scenes of a cruise ship.

Ironically, as impressed as I was, Wonder of The Seas still uses what’s considered a manual system that requires lots of humans. We were told that the newer ships have automated assembly line machines.

This was a new addition to the tour, and there was some confusion with the timing. We got there as the show was closing. It was interesting to see behind the curtain, but I’ve been behind the curtain of much larger productions, so this part of the tour was not as fascinating. I didn’t take any photographs on this part of the tour. 

I can’t lie; I’ve always wanted to go on The Bridge of a cruise ship. Something about uniforms (especially American uniforms) has always captured my attention. Ok, fine, I’ve always been attracted to American men in uniform! An Officer and A Gentleman, anyone?

You’ll get to meet the captain; if you are lucky, you’ll chat with him. At a minimum, his team will pose for you.

While I got to see The Bridge, it was not as artsy-farty as I expected. It’s decadent and plush but a bit boring. Maybe the décor was not my style. I’m not sure, but other than the views of the ship (not the men), this was not my favorite part of the tour.

And, even if the captain was smoking hot. It would not have mattered. See the section below on what you need to wear. I looked like a right plank (pun intended) on this tour!

Clothing Requirements

• High heels, flip-flops, and open-toed shoes are not permitted.
• Shorts and skirts are prohibited.

Well…. Here’s a problem. I only wear flip-flops, I don’t wear pants, and I do not own a pair of sneakers, nor do I own a pair of shoes that are not open-toe. A girls’ girl dress-only girl who gave up shoes years ago! I do wear leggings sometimes, but who takes leggings on a cruise?

To my horror, my choices were either not go on tour or get creative.

Here’s what creative looked like. Me in Brian’s loungers’ pants, in his boots that are at least five sizes too big. And a beautiful peacock blue dress on top of it all. Pretty confident that my makeshift outfit that met the criteria was about as safe as jumping off the Empire State building. But it was required!

Jokes aside, if you plan to take The All Access Ship Tour make sure you pack the right clothes!

Closing Thoughts

The All Access Ship Tour was one of the highlights of our cruise. It’s not a tour I think I would do on every ship. At some point, it would become repetitive. This said, it was money very well spent, and I know I will do it on another ship!

Although cruising isn’t for everyone, it can be a great family travel option if you’ve never tried it before. Cruising is a fantastic way to enjoy well-earned time off , and there are many reasons to try it!

While engine room visits may not be available on all cruise lines, several cruise companies recognize the curiosity and interest of their passengers and offer this unique opportunity. Royal Caribbean, Carnival Cruise Line, and Norwegian Cruise Line are among the popular cruise lines that allow engine room tours. Each cruise line has its own policies and procedures regarding these visits, so it’s advisable to check with the specific cruise line before booking your trip to ensure engine room tours are available.

Booking and Availability

To make the most of your engine room visit, it is advisable to pre-book your tour once you have confirmed your cruise reservation. Engine room tours tend to be in high demand, and booking in advance ensures that you won’t miss out on this captivating experience. Some cruise lines also give priority to their frequent cruisers, allowing them to book the tours earlier than other passengers.

It’s important to note that due to capacity limitations, the number of engine room tours available may be limited. Therefore, it’s advisable to secure your booking at the earliest opportunity to avoid disappointment.

Cost Associated

The cost of engine room tours can vary depending on the cruise line and the specific package or tour you choose. Some cruise lines may include the tour as a complimentary activity, allowing passengers to explore the engine room without any additional charges. However, on certain cruise lines, visiting the engine room may attract an extra fee. Typically, if additional charges apply, they are minimal compared to the overall cost of the cruise.

When booking your cruise, it’s advisable to check the details of various packages to see if the engine room tour is included or if there are any additional fees associated with it.

What to Expect

When visiting the engine room, it’s essential to set realistic expectations to fully enjoy the experience. The duration of the tour may vary depending on the cruise line and the depth of the visit. On average, engine room tours last between 30 minutes to an hour, providing ample time to soak in the sights and sounds of this intricate mechanical wonderland.

As you venture into the engine room, you’ll encounter a myriad of equipment that powers the ship. From massive engines and generators to fuel storage areas and control panels, you’ll gain a new appreciation for the intricacy and scale of the machinery that keeps the vessel afloat.

How ships float, avoid icebergs, & other questions from our not-so-scientifically-inclined writers.

Our virgin voyages engineers are dishing on what actually makes cruise ships work..

As a Sailor on one of our cruises, there’s some stuff we don’t want you to worry about. Cooking for yourself, for example. Stressing about work. And we certainly don’t want our Sailors to be preoccupied wondering, “how do cruise ships work?” or “no seriously, how do they stay afloat like that?” Our engineers worry about these things so you don’t have to. But even if you’re not contemplating the Archimedes Principle of positive buoyancy while you’re soaking up rays on the pool deck, you might have always wanted to know how cruise ships stay afloat, or how they avoid obstacles at night. These are interesting questions, even for the non-mechanically inclined.

Since we’re in the cruising business, we find this stuff fascinating, too. That’s why we interviewed Chief Engineer Rhea Wilson and her team to get the inside scoop on everything related to ship mechanics and operations. They break down how cruise engines work, where the water you’re drinking comes from, how cruise ships detect icebergs, how they avoid icebergs, and — yeah, a lot of other iceberg-related questions. If you knew nothing about ship mechanics before, that’s about to change. This one’s for all the nerds out there.

How cruise ships work: An interview with our Chief Engineer

Maybe a stupid question, but how does such a massive boat stay afloat, anyway?

Engineers : Science. Archimedes Principle to be exact, positive buoyancy. Basically the bit of the ship in the water weighs less than the weight of water it replaces (lots of tanks to create buoyancy). Why a tree trunk will float but a brick will sink despite the tree trunk weighing more.

Where is the engine located, and how are cruise ships powered? 

Engineers : Cruise ship engines are located near the bottom of the ship as they are heavy, and they are usually towards the aft of the ship. Cruise ships use Diesel-Electric propulsion systems. The main engines are generators which produce electricity which then powers the azipods. VV ships have 4 engines and  2 azipods. There are 3 bow thrusters to provide maneuverability when arriving/departing a port.

Azipods are a motor with a built in propeller and rudder. The electrical power created by the engines drives this big azipod motor which turns the propellers, and pulls the ship forward. Basically think of how a jet engine pushes air across a plane wing — that's how an azipod and propeller pushes water across the rudder and drive/steer the ship. They can turn 360 degrees for maneuverability, and the rpm of the propeller varies depending on the required ship speed.

People tend to imagine engine rooms looking like the one on Titanic, with sweaty laborers shoveling coal into the engine. What does a cruise ship engine room actually look like?

Engineers : Well it can be a hot working environment, there is a lot of heat generating machinery in the engine rooms. However a modern engine room is bright and clean and nothing like Titanic. The engines are a large part of the engine room, but the whole lower part of the ship is the engine rooms and compartments with auxiliary equipment used to supply a whole ship. So fresh water generators, a wastewater treatment plant, stabilizers for minimizing ship movement etc, not only the engines like you see in the movies.

Speaking of Titanic, what technology is in place to keep cruise ships from hitting icebergs?

Engineers : Much better equipment for detecting objects in the water. Be it small craft, other large ships, or icebergs. That and proper binoculars for the lookouts.

Cruise ships are pretty huge. How quickly could it change direction and navigate around an iceberg, if one was detected?

Engineers : As above, the azipods make a large ship really maneuverable for it's size, much more so than a ship with conventional propellers and rudders. 

If the ship did hit an iceberg, and started taking on water, what would happen? 

Engineers : There are 5 main vertical zones along the ship, and split further into compartments. Every one of these compartments are capable of being fully isolated in case water came in and the ship would still be operational. There are regulations in place for essential services to stay functional in case certain sections were lost to fire or flooding.

Okay, enough about icebergs. We don’t even sail near them. People are more aware now than ever of their carbon footprint. What are cruise ships doing to reduce emissions ?

Engineers : There are stringent rules and regulations on emissions globally and locally to the ports the ships visit. There are advanced gas cleaning systems always in use to comply with these rules.

If someone fell overboard and the ship needed to stop, how long would that take? No one will, but I just have to ask.

Engineers : The requirement for a complete stop from full speed is 15 ship lengths, but the Virgin Voyages ships take less than half that for a stop from full speed.

Where do the ship engineers (and other essential ship operating staff) sleep when they’re not working? 

Engineers : The majority of ship engineers/essential staff have accommodations close to the Engine Control Room, so they are close to their workplace. Most engine officers have an alarm fitted in their cabins which is activated from the ECR in case of technical emergency. Usually the deck below the main passenger decks, so with a porthole for daylight :)

Is there a giant 12,000,000,000 lb anchor like you see in movies?

Engineers : Not so much. There are two anchors by the bow, but they're not comically large. An anchor's “weight” to keep a ship in place is in the chain, not the anchor itself.

Where does the drinking water come from on a cruise ship (please tell us it’s not toilet water)?

Engineers : There are large Reverse Osmosis plants which take in heavily filtered sea water, and then after many processes produce fresh water. This fresh water is then treated to public health requirements and standards. So no, it's not from the toilet water. That water never goes anywhere near the potable fresh water.

Sometimes I’ll see the ship captain dining in a restaurant, or wandering around the boat. When he’s gone, who’s keeping the ship away from icebergs?

Engineers : Well there is a whole team for deck and engine departments, and the Captain can't be navigating the whole time. There is a watchkeeping team – consisting of deck officers on the bridge and technical officers in the ECR – 24/7 keeping the ship away from icebergs and the lights on while the Captain is out having dinner.

Wow, we certainly learned a lot about cruise ships!

Cruise cabins and suites

Cruise ship rooms, floor plans, photos.

CruiseMapper's cabin and suites section allows you to explore cruise staterooms by ship. Each page provides extensive information on all passengers accommodations on a particular vessel, including floor plans, room types and categories (grades used upon booking), cabin sizes, deck location. Also provided is an extensive review of all ticket price inclusive en-suite amenities, along with furniture details and additional / bonus perks (if available).  

Here you will find brief descriptions by category of all stateroom types that can be found on cruise ship deck plans . You will find more information and many useful tips on staterooms at our best and worst cabins article. Here you can search for a particular ship (via the above search bar) or you can skip the introduction (explanations) and go down directly to our list of large passenger ships' cabin pages .

Cruise staterooms booking rates are usually based on deck location. Lower-deck accommodations are the cheapest. Midship rooms cost more. Balcony staterooms and Suites located aft or forward are the most expensive. Most cruise companies (especially those with large-sized vessels in the fleets) divide the main cabin types into subcategories. These grades are marked with numbers (like for balcony cabins - B1, B2, B3, B4) and are displayed on the deck layouts with different colors.

Cruise ship suites

Cruise suite accommodations are premium grades cabins. They are usually larger in comparison to balcony staterooms and feature more amenities. As a rule, suites have a full-size bathtub, larger shower, bigger closets and balcony (some have 2 private balconies). Amenities include coffee makers, premium sound systems, large-size TVs, complimentary butler service.

Loft Suites (aka Duplex Suites)

Loft Suites are "duplex suites" (on two levels) and available on the world's largest passenger ships of Royal Caribbean's Oasis-class and Quantum-class. The following layout is of Harmony of the Seas and its largest accommodation - the Royal Loft Suite.

Grand Suite

Twin beds in this type of cabin can be joined in a king bed. Grand Suites have also a double sofa bed and large private balcony, sitting area with 2-armchairs and a coffee table, desk, dressing area with vanity, walk-in closet, safe box, TV, phone, refrigerator, mini-bar, private bath with whirlpool tub and shower, patio chair and table, balcony lounge chair, pillow menu, bathrobes, hairdryer. See below the magnificent Oceania Marina ship's Owner Suite plan.

2-Bedroom Mozart Suite (largest stateroom on a riverboat)

World's largest accommodation found on a riverboat is Riverside Mozart 's French Balcony Suite. The vessel has two such accommodations, each sized 885 ft2 / 82 m2. Must be noted, that the stateroom is combined with an adjacent French Balcony cabin.

Penthouse Suite

Penthouse Suites have a twin beds configuration (beds can convert to queen). The other features are a large balcony, dressing area with vanity, sitting area with armchair and coffee table, wall safe, mini bar, private bath with whirlpool tub and shower, television and phone, refrigerator, bathrobes and hairdryer. Some cabins are without whirlpool tub, sofa or coffee table.

Balcony staterooms

Most balcony cruise ship cabins feature floor-ceiling sliding glass doors leading to a private step-out veranda. The balcony also is furnished with a table and pair of chairs/loungers. Standard balconies are separated by dividers. As sizes, balcony cabins on cruise ships vary, with those on Princess and NCl ships being among the smallest compared to other big-ship lines. In our cruise deck plans, we also list room sizes and the size of the balcony. Balcony – Apart from the balcony they can offer You twin beds that can be converted to King-size bed. Balconies also provide sitting area with chair and coffee table and private bath with shower, as well as closet/wardrobe, electronic safe box, mini bar, television and phone, sofa, bathrobes, hairdryer. Most verandas are between 30-60 ft2 ( approx 3-6 m2). Below are shown the layouts of the Anthem ship's Deluxe and Accessible balcony cabins.

Premium Balcony

Premium Balcony cabins also have twin beds that convert to King-size, their wraparound balcony enfolds the stateroom. Balcony's windows are often floor-ceiling and wall-to-wall.

Cove Balcony Staterooms

Cove balconies, unlike Balconies, have two patio chairs and a table. The rest of the stuff is identical. First of all-balcony, and again twin beds that convert to king, sofa, private bath with shower, safe, closet, mini bar, television and phone, sitting area with chair and coffee table, bathrobes and hairdryer.

Cove Balcony rooms are CCL-Carnival's specialty, available on some of the "Fun Ships", and are interesting because they are located on lower decks (thus closer to waterline).

Oceanview staterooms

Oceanview cabins: as sizes are similar to Interior staterooms on cruise ships, but each of them has a Porthole or normal window (both types do not open). Their window sizes also vary by line and ship. On some ocean ships and some luxury river ships, such staterooms feature floor-ceiling windows. Oceanview rooms' window sizes are usually 4x3 ft (1,2x0,9 m). As furniture, Oceanview cruise cabins have twin beds that convert to King-size, sofa, TV and phone, sitting area, safe, mini bar, private bath with shower, and also a washroom with sink and a junior tub, bathrobes and a hairdryer and of course a picture window. You should take a look at the cruise ship deck plans again as Cabins of 5A category have two porthole windows. Unlike deluxe, there is no washroom with sink and junior tub. Below are the layouts of Ovation of the Seas Oceanview cabins (categories standard, large, and superior).

Deluxe Oceanview

These cabins have no balconies but still can offer a marvelous view through their picture window as well as twin beds that convert to King-size. However, beds in Category 6N can't be joined (to King) and sleeps max 5 people.

Other amenities include sofabed, TV, phone, seating, safe, mini-bar, a bathroom with shower, a washroom (with junior tub), bathrobes, hairdryer.

Scenic Oceanview

The interior is the same - twin beds convertible to King-size, picture window, sofa, TV, phone, seating, safe, mini-bar, bath with shower, washroom with sink and junior tub, bathrobes, hairdryer.

The difference is that Scenic Oceanviews are larger.

Inside staterooms

Inside cruise ship cabins' best feature is their price - you book them with the line's cheapest rates available. These cruise accommodations don't offer window views. Still, on some of the newest cruise ships of Royal Caribbean and Disney, there are categories Interior staterooms with a "virtual window", which is a large LED screen displaying outside cam views. The screen doesn't have TV functions.

On some Carnival ships, there are Inside cabins with a "French Balcony" (with opening glass doors). Also, some "interior staterooms" are actually Oceanview (with a non-opening window), but since their views are obstructed, they are booked as Interior. On Royal Caribbean ships, some Inside cabins have a window looking out to the ship's interior promenade (street)

Inside cruise cabins are fitted with twin beds (convertible to King or Queen), private bathroom (shower), sitting area. Next are shown the layouts of Interior rooms on Harmony OTS .

Small Interior Stateroom (as the name implies) is the least spacious standard cabin category on cruise ships. These cabins have two beds – (upper and lower), private bath (WC/shower), a small sitting area.

Single cabins (Studios)

Single occupancy staterooms could be either Inside or Balcony. Some river cruise lines even offer single suites (booking with single occupancy rates). The most famous liner having plenty of single cabins (designed specifically for solo travelers) is Norwegian Epic .

This huge vessel has a total of 128 "Studios".

Next are shown layouts of Quantum OTS single-occupancy cabins (balcony and interior).

Connecting cabins (for large families)

The next layout shows RCI's "Family Connected Junior Suite" plan ( Quantum OTS ). Ship's main cabin grades (Balcony, Oceanview, Inside) are all combined here into a 10-person "Family Suite". The layout also shows the exact positioning of furniture, 3 baths (1 with hot tub), large seating area, 2 double-sofabeds, 2 connecting balconies.

How to choose cabins on cruise ships?

If you are planning a cruise, booking a cabin is certainly as important as picking up the cruise line (brand) or the boat. Before you take that decision, consider some issues related to your own personality and the other people traveling with you.

• The first important thing you have to be honest with your conscious is whether you can get seasick .
• Secondly, what type of person you are and what exactly do you intend to do onboard? Are you a party type or you just would like to spend several calm days at sea, away from the office jungle on land. Would you enjoy the pool with its all opportunities for contacts or you would rather have a rest lying at a balcony?
• No matter the stateroom type, it could still be noisy or make you seasick. The more central and lower position your cabin has, the more stable it is.
• In case you and the rest of the family members / friends are thin or you just don't intend to spend too much time in the cabin, you can pick a small one. Usually, staterooms are able to house no more than 4 people. Two passengers pay full fares and the other receive discounted rates.
• If you need stateroom for 4+ passengers, connecting cabins are the best option, and it will cost you less than a suite. Bathtub-fitted cabins are not so many per vessel. All cruise deck plans show such information (bathtub, sofabed, double bed, bunk beds, etc).

Noise issues - which cabins on the ship to avoid?

If you are a party type and louder sounds are not bothering, everything would be OK. If you organize a family voyage, however, you should look for a cabin away from the noisiest areas in the cruise ship deck plans. The first thing to look for in the cruise ship plan is the engine room location. Along with the noises, there are also vibrations.

Staterooms under discos, sport playgrounds, gym centers are usually very noisy. Cabins under Lido Deck (aka Pool Deck) are also among those to avoid. The buffet restaurant on this deck generates noises from moving tables and chairs and tableware. Staircases are also very noisy.

Take a good look at the cruise ship deck plan - room location is crucial!

Cabin's deck location is of great importance. Lower and more central-positioned accommodations are more stable. However, "cool cabins" are usually on higher decks, which means spending more money won't necessarily save you from seasickness.

Stern cabins (aft) have the largest balconies. Forward suites provide the same view as from the Navigation Bridge (wheelhouse). Some cabins are with limited / obstructed seaview due to lifeboats or other equipment.

Guarantee staterooms - take your chance!

If you are not set on selecting something particular and location is not a priority, you should not investigate the cruise ship deck plan so cautiously. The so-called ''guarantee'' cabin grades can turn to be among the best booking options. The "guarantee stateroom" booking allows you to pick up a category, not a cabin. In case the category is sold out you'll be proposed a higher category lodging. The first cabins to be booked are both the cheapest and the most expensive ones, be aware when you choose to test your luck. However, it could be a bit risky so it's more reasonable to get back to the cruise ship deck plans.

Shipboard facilities

If want to cruise with your children you'd better book a stateroom close to kids entertainment facilities. Cruise ship deck plans can once again help you to choose from the many opportunities created to meet passengers' requirements. Spa cabins are recently available for instance. Passengers get free access to the steam room and other connected facilities. These cabins are of course close to the SPA and you can move between in your bathrobe only.

NCL's The Haven and MSC's Yacht Club accommodations are located within an exclusive complex and offer ''ship within ship'' amenities and services. Passengers (who can afford them) enjoy private sundecks with swimming pools and jacuzzis and exclusive facilities like restaurants, bar lounges, gyms and spas.

Prefabricated cruise ship cabin

On May 24, 2016, a new "Lightweight Composite Cabin" design was unveiled in Southampton, England. The innovation was funded by the UK Government. Involved in the cabin's designing, engineering, manufacturing and furbishing were the companies Carnival UK ( Carnival Corporation 's subsidiary), Gurit Ltd (global composite materials supplier), Lloyd's Register Group Ltd (technical / business services, maritime classification company), PE Composites Ltd (composite designer / manufacturer), Trimline Ltd (marine interior refurbishment specialist) and the University of Southampton.

The new modular cabin prototype is half the weight of a typical cruise room. It also fully complies with the FTP Code's requirements (International Code for the Application of Fire Test Procedures). Reducing the ship's topdecks weight is an important issue for naval architects as the trend for building large-capacity cruise vessels continues. The new (prefabricated) module's halved weight opens up opportunities for adding more passenger rooms to newbuild ships, without adding to the ship's DWT weight.

19 Shocking Cruise Ship Secrets And Tips I Learned After Going On Seven Cruises

Hey! I'm Spencer , and I just got back from my seventh cruise. I've seen and learned a lot of really cool behind-the-scenes secrets while traveling the world on these ships, so I wanted to share some of the most interesting ones with you here, including some tips that may be helpful for your own future adventures. Enjoy!

Spencer Althouse, Instagram: @spenceralthouse

For context, I've traveled on four different cruise lines: Royal Caribbean, Princess, Holland America, and now Carnival. My most recent trip was a seven-day sail aboard Carnival Firenze, which traveled throughout Mexico. This was my first time on Carnival, and I somehow managed to get a private tour to areas of the ship that even the most elite VIP passengers will never, ever see. Here are some things I learned along the way.

1. First of all, yes, most cruise ships have both a jail and a morgue on board. These were the only areas of the ship where I wasn't allowed to visit (trust me, I asked multiple times) because they're strictly off limits unless you find them the old-fashioned way...by getting arrested or dying. I didn't want to take those chances, but I did find out that shorter cruises tend to see a LOT more action in the jails (aka "the brig"). Guests typically treat shorter sailings as more of a party by taking advantage of unlimited drink packages, and more alcohol = more fights on board, so needing a jail totally makes sense.

In terms of the morgues, those are usually located on one of the ship's lowest decks. Think of these as giant refrigerators that, depending on the ship's size, can house anywhere from a couple to nearly a dozen bodies. The majority of these deaths are obviously of natural causes – for reference, as of 2018, fewer than  25%  of global passengers were under the age of 30 – but the average age of a cruise ship passenger is getting younger and younger every year now.

2. The higher you are on a ship, the more movement you'll feel, so if you're someone who tends to get motion sickness then you should definitely book your room on the lowest floor possible (just not in the morgue). I've personally never had an issue with motion sickness on a cruise, but I'll occasionally see passengers with at-sea patches behind their ears for help. Contrary to what you might think, though, you'll probably get the best night's sleep of your life on a cruise. Yes, there's a ~very~ slight rocking, but it'll feel sort of like you're a baby again who's being lulled to sleep in a cradle. Just trust me on this one.

This is a photo of what my cabin looked like. I also included a picture of my bathroom, which was a little bigger than I thought it'd be. The shower itself was a pretty decent size and left me with room to spare (if you want a point of reference, I'm 5'11" [a real 5'11", not a Tinder 5'11"]).

I was in a balcony room on Deck 6, and, again, I had no issues with motion sickness. I've also sailed on higher deck levels before (up to Deck 9) and didn't have any issues then either. In terms of where on each deck you should book your cabin (i.e. midship, aft, or forward), that doesn’t actually matter because you won’t really feel the motion differently in other spots on the same deck.

3. But I promise that you probably won't even have to worry about getting seasick. I got a private tour of the ship's control room, and I learned that they do a lottttt to combat any movement from the waves. For example, ships try to hit waves at a 45-degree angle because that's apparently the most effective way to help break them up and cut down on the extra motion. Ships also have stabilizers that can extend outwardly (picture, like, wings on an airplane), which help to keep things super, super stable.

Think of these stabilizers like fins on a fish, so they help each ship glide along the water. I spoke with the captain and some of the engineers in the control room, and they explained that the stabilizers require extra fuel and also decrease the speed of the ship, so they tend to not use them unless the water is pretty rocky.

4. Before you book a cruise, you should know that they're sort of like buying a car: you can negotiate! Basically, the price you see online should almost never be the price you pay (though they often offer great discounts that you should absolutely check out!). Instead, it's best to call and book your trip with an actual person (i.e. someone who works for the cruise line, a travel agent, etc.). For example, travel agents are usually free, and they can get you a ton of bonus perks and huge discounts on rooms for a fraction of the original price.

A lot of cruise lines occasionally offer "buy one, get one" discounts, as well as a ton of other sales around specific holidays. There are also a bunch of sites where you can book discounted sailings to fill the leftover rooms that haven't sold, so just do a little research. Also, places like BJ's and Sam's Club offer trip discounts if you have a membership card to their stores, so take advantage! I booked a previous cruise through one of them a few years back and got a massive discount for my room, onboard credit, and free gratuities. It pays to save!

5. And if you ever want a "free" cruise then you should definitely hit up the casinos on board. It's super common to get extra perks on future sailings (like free Wi-Fi, drink packages, or even entire trips altogether) if you're someone who gambles a lot. Basically, each bet is tied to your personal cruise card (i.e. your room key) every time you play the slots or put money down at a table game. Your total winnings are tracked on that card, and you'll earn points based on the amount you spend. The more you gamble, the more likely you are to get offered those extra perks.

I'm always mesmerized by cruise casinos because they literally created their own mini Las Vegas on board. Like, there are pit bosses and thousands of tiny security cameras and everything else that a real casino would have. The only downside is that these casinos are obviously much smaller than what you'd find in Vegas, so they probably won't have every table game you're looking for. Yes, they have roulette (my favorite) and craps and half a dozen variations of poker, but I still haven't found a pai gow table on board. Maybe next time!

6. The cool thing about cruises – especially for people who are ages 18 through 20 – is that they can sort of make their own laws while at sea. This is known as Maritime Law. For example, gambling at the casino is only allowed once the ship is at least 12 miles from land, but that also means they can lower the age limit from 21 to 18 while in international waters. The legal drinking age on most cruise ships is also 18, not 21.

There were actually two separate casinos on my recent Carnival ship. The larger area allowed smoking and had hundreds of slot machines, a ton of table games, and "adult" claw machines that replaced stuffed animals for huge wads of cash. The other casino, though, was the designated non-smoking area, and even though it was much smaller it still got the job done.

I'm still surprised that people are allowed to smoke in the main casino (there was also a cigar room on board but on a different deck), but, hey, I guess that's Vegas, baby.

7. There are themed cruises for pretty much anything you could ever imagine – for example, Royal Caribbean offers an immersive Star Trek cruise , and Norwegian is even offering a 2,300-person nude cruise next year – but on "regular" cruises there are certain SFW guidelines that guests (and staff!) need to adhere to. For instance, it's forbidden for staff to hook up with guests on board. Doing so would result in a pretty quick termination of their employment contract. Also, there are thousandsssss of security cameras on board, so, like, good luck trying to get away with it.

Years ago I befriended one of the gym trainers on a cruise, and he revealed that he actually managed to hook up with a guest on board. Because there are so many security cameras, it would have been impossible for either of them to visit the other person's cabin without getting caught, so he told me they hooked up in a random towel closet. I guess this is why a lot of cruise ship employees end up dating each other instead of the guests, because it's way less risky and a lot more convenient.

8. Speaking of hooking up on board, there was so much "swinging" happening between couples that a lot of cruise lines had to create training programs for the staff. Basically, decorating cabin doors is a pretty common thing for elite cruisers (as pictured below), and the secret symbol for swingers is an upside-down pineapple. As a result, a lot of couples would decorate their doors with upside-down pineapples to let other guests know that they're open for fun. According to the high-up staff member I talked to, employees on their previous ship were instructed to report any pineapple decorations found on board.

That staff member also told me that this whole issue started because some couples would leave their cabin doors ajar as an invitation for other swingers. However, the housekeeping staff (who are truly, truly incredible!) unknowingly entered while the couples were ~doing the deed~. Employees on cruises typically come from all over the world (on my Carnival ship, they had staff from over 100 different nations), which means they also have certain religious backgrounds. Spotting and removing these pineapple decorations was done in an effort to protect the staff and their religious beliefs.

9. You have to remember that these ships are basically floating cities, so they have everything you could ever want. Like, I've been on ships with a freaking ice skating rink before, and my recent Carnival sailing had an 18-hole mini golf course on the top deck. Also, itineraries are left outside each guest's stateroom every morning, and they list alllll the activities you can do (or not do!) that day. Want to try your luck at bingo? Have at it. Always wanted to go to an art auction? They've got those too. Want to prove your sports, movie, history, Harry Potter , Friends , or just general knowledge at dozens of trivia events? Be their guest! I promise that you'll never be bored on a cruise.

Cruises even have LGBTQ+ mixers, silent disco parties, wine tastings, and cooking classes. There are also discreet meetings for those who are sober or in recovery. For example, Alcoholics Anonymous meetings are labeled as "Friends of Bill" events on each ship's itinerary (this is a nod to Bill Wilson, who co-founded AA).

10. Keep in mind that items on cruise ships are definitely more expensive than what you'd normally pay on land. The spa and salon on my last sailing, for example, charged $175 for a 75-minute Swedish massage and $99 for a "red carpet blowout." If that's somehow in your budget then have at it, but if you want heavily discounted prices then you should book those treatments on days when the ship is at port – this is when most passengers will be off the vessel, so a lot of cruise lines offer discounted treatments to help fill up those time slots and prevent people from hitting up the spas on land. Again, though, you can typically negotiate for certain spa perks when booking!

Every cruise I've been on has had a full-fledged shopping mall on board. There are dozens of stores that sell everything from designer goods to any type of candy or snack you could want. Again, these prices are pretty steep, so if you forget to bring sunscreen then it's probably best to just wait until you get to the next port. Even so, there are definitely ways to save money while cruising!

11. The more you cruise with a specific line, the more perks you'll get (like free room upgrades, priority access, unlimited internet, and on-board casino credit). These loyalty programs are based on the number of days you sail with each line, so, for example, everyone on their first Carnival cruise is in the Blue tier, then they reach Red status on their second sailing, and once they hit 25 days on board they'll reach the Gold tier. Platinum is achieved after 75 total days of sailing, and Diamond status is for people who've sailed for at least 200 days. I met so many Diamond members that my jaw kind of dropped – like, these people LOVE cruises and go on several a year. It isn't just a vacation for them; it's a full-on hobby.

While doing some research, I also found out that Royal Caribbean even has a "Pinnacle Club" for people who've sailed for over 700 days on their ships, which, holy crap??? So if you're prepared to spend the equivalent of two years on a ship (which kind of sounds like a dream to me, to be honest), then get ready for the ultimate form of perks and luxury.

12. Another way to save money is by booking your shore excursions through third-party vendors. Booking through the ship is definitely the most expensive route, but it's also the safest because you'll never have to worry about the ship leaving without you. Ships have strict docking schedules to follow on port days, so they ~will~ leave without you if you aren't back in time. Otherwise, you're in charge of making it to the next port of call on your own, so good luck. If you have a short port day and are only docked for a few hours then I'd suggest booking through the ship so you don't risk getting left behind.

Cruise lines display all excursion reviews from past passengers on their site, so this can be such a helpful resource to prevent you from booking something that sounds good on paper but is underwhelming in reality (been there, done that). I typically book excursions through vendors who are waiting outside as soon as everyone gets off the ship, but I do a lot of research ahead of time and will often find things to do that aren't even offered by the cruise.

You obviously don't have to go on any excursions at all either. There have been plenty of times when I've simply explored on my own by walking around, grabbing a bite from a local spot, or relaxing at the beach. You also don't even have to leave the ship if you don't want to. In fact, port days are incredible for peak relaxation on board because it's way more quiet, and you'll never struggle to find an open lounger by the pool. Free is my favorite number, so remember that there will always be plenty to do no matter your budget.

13. You should know that there are some banned items you simply can't bring on a cruise. Before boarding, you'll quickly go through security, sort of like a relaxed version of TSA at the airport. The whole process typically only takes a few minutes. Depending on the cruise line, you're usually allowed to bring up to 12 cans of non-alcoholic beverages (my friend brought a six-pack of ginger ale in case she felt seasick, and those made it through just fine. I also saw a bunch of Diet Coke-obsessed people with whole cases, and those made it through too). Candles, hot plates, and the obvious knives, guns, fireworks, etc. are all banned as well.

Bottled water isn't typically allowed through security when checking in, but you can absolutely buy it on board. More importantly, though, there will be plenty of free fill-up stations for your water bottle throughout the ship, so that's an easy fix. I can't stress enough how necessary having a water bottle is, so make sure you bring one (both for your regular onboard living but also for when you leave the ship on port days).

14. Also, don't even try to sneak alcohol on board because you'll definitely get caught. Each ship is different, but for the most part you're only allowed one unopened bottle of wine or champagne in your carry-on. If you buy spirits while at port then you'll have to check them when you get back on the ship, and they'll be returned when you disembark. After all, most cruises only become profitable after adding up their total alcohol sales and casino winnings (I guess it helps that Carnival's 27 ships, for example, sell over 14,000 margaritas each day). For reference, a standard cocktail on my last trip was about $13, and the unlimited drink packages were about $60 a day.

Depending on the cruise line, these unlimited drink packages can range from $55 to over $100 each day. These include specialty coffees, soda, beer, wine, cocktails, and the works. Remember, some people treat cruises like parties (my last sailing had FIVE different types of espresso martinis at the bars, so, like, I sort of don't blame them), and they certainly try to get the most bang for their buck. I've done the math, and you need to have at least five specialty drinks per day to make the unlimited package "worth it."

Non-alcoholic drink packages also exist, like a $9.50-a-day pass that'll get you unlimited sodas. But there are free drinks on board, whether you're at the buffet or sit-down dining, like tap water, brewed coffee, hot teas, hot chocolate, lemonade, iced tea, fruit juices (fresh-pressed ones will cost extra), and milk.

15. Cruise ships obviously make tons (and I mean that literally, not figuratively) of food every single sailing. After all, the average ship holds about 3,000 guests and 1,000 crew members. An employee who I spoke with said Carnival serves about 30,000 burgers every single day, and they'll make over 1.3 million pounds of French fries each year. There are free sit-down restaurants and buffets on board, but there are also specialty dining options that guests can pay for, like hibachi and steak houses. My family always sticks with the free dining options, and I think non-cruisers will be shocked by how good the food actually is, but the best part is that you can order several appetizers, entrées, and desserts per person, so, like, you'll never leave hungry.

All of that food used to mean there's a lot of food waste, but that's not really the case anymore. In fact, a lot of ships are working on how to become more and more sustainable and environmentally friendly. For example, rather than dumping food waste in the water, I saw on my private tour that Carnival has a "food digester" room. Basically, it's a massive machine filled with bacteria that'll break down all the food scraps, just like how your own body breaks down food. Yes, it smelled just as bad as you probably think it would.

Similarly, some ships are even using artificial intelligence to make their sailings more environmentally friendly. While in the control room, one of the engineers told me about how their ship is using new AI that basically studies each sailing so it can recommend new ways to make future voyages as efficient as possible, like by creating energy-saving routes and so on.

16. If you're worried about potentially having bad weather on your cruise then, well, think again. Yes, there's obviously a lot to do inside, but a lot of ships also have retractable roofs on their top decks. So, if it's ever too cold, rainy, or windy then they can usually cover the entire lido deck (i.e. where most of the pools, jacuzzis, and lounge chairs are), which means you can relax "outside" even in the terrible weather. A lot of ships also offer indoor pools and adults-only sections, so, like, you'll totally be set no matter what.

My recent cruise had a regular pool and jacuzzi setup on the lido deck, but there was also another section at the back of the ship with one more pool and two more jacuzzis. There was even a "Serenity" section at the top deck, which served as an "adults-only retreat," meaning passengers younger than 18 weren't allowed. That area unfortunately filled up super fast on sailing days, so if you ever go on a ship with one I'd definitely recommend getting there early.

A lot of ships also offer private areas and decks that are exclusive to only those who book certain rooms. This secluded area was much quieter, super luxurious, and actually felt like I was on a totally different ship. If you're booking a cruise and see that there's an exclusive area, you should absolutely ask about how to get access ahead of time.

17. It's tradition for every ship to have a celebrity godmother or godfather who christens the boat before the inaugural launch, and those celebs are typically rewarded with free cruises for life (!) on that specific vessel. For example, Oprah Winfrey is the godmother of a Holland America ship, and even Audrey Hepburn was the godmother of a Princess ship. Carnival only has two godfathers, and they're fittingly both for their Italian-themed cruises: Jay Leno and now Jonathan Bennett. Christening the ship used to entail smashing a bottle of champagne against its hull, but the night before my cruise I got to watch Jonathan Bennett pour a bottle of champagne over the ship's bell to toast its safe travels instead.

Judi Dench is also the godmother of a ship, and it famously took her three different attempts to break the bottle of champagne against its hull, which then sprayed all over her. That was in 2002, so I think switching to this new christening method with the ship's bell is definitely less messy.

18. One of the most unique parts about cruising is that you'll typically find a cool towel animal waiting for you after returning to your cabin every night. The housekeeping staff are all trained in towel folding, so after dinner you'll have a new animal sitting on your bed or, in my case, hanging from the ceiling. A lot of ships even host towel-folding classes during sailings so guests can learn how to make the animals themselves, and how-to books are also available in the bookstore. I found out that Carnival's housekeeping team makes about 15 million towel animals every single year, which, holy crap.

One morning while on my way to the gym, I walked through the lido deck and saw hundreds of towel animals sitting on every single lounge chair outside. There were monkeys and elephants and dogs, but the most impressive towel animal that I saw was an octopus. I still have no idea how they managed to pull this off, and I'm genuinely so impressed.

19. And finally, the most important thing you should know about cruises is that there are several self-serve ice cream machines on board, and they're all completely free (and unlike McDonald's, these machines are always working!). If you're like me and deserve a sweet treat after dinner – or, let's face it, after or even before breakfast – then you understand how big this is. After all, you're on vacation, so you should be eating as much ice cream and frozen yogurt as you can get your hands on.

I worked at Dairy Queen for a few summers as a teen and genuinely loved it there, so having the ability to serve myself a cone whenever I wanted made me feel at home. And if you're more of a gelato person then I totally understand! Luckily for you, cruises have got you covered. My ship had a freaking gelato spot on board, and they expect to serve about 750,000 scoops this year, but I have a feeling half of them were because of me.

That's it! If you have any other cruise travel tips that have worked for you, please feel free to share them in the comments. Thanks!

Modular homes: What they are and how to finance them

A modular home is built in a factory and assembled on-site. Learn how much it costs and how to finance it.

I've stayed in 3 types of rooms on cruises, and the cheapest was never worth it. Here's what to book instead.

• I'm a frequent cruise traveler who's stayed in a variety of onboard accommodations.
• The least expensive rooms have no view and are usually cramped, especially if shared by a family.
• Splurging on a higher-category cabin on my last cruise was the best decision I made.

Automatically booking the cheapest room on a cruise ship without doing proper research first can ruin a trip. 

As someone who's been going on cruises for over 10 years, I've learned that the price tag for these vacations can vary based on a number of factors — from cruise line to trip duration to room category.

Staying in the most standard-level cabin seems like an obvious way to keep costs down. But after trying out three different room categories, both with and without my kids, I've found that a ship's least expensive option is almost never worth it.

Based on my experience in three different cruise-room categories, here are the ones I recommend skipping and the ones I recommend splurging on.

Interior staterooms are limited in space and privacy

The standard (and least expensive) room on any cruise ship is typically called an inside or interior stateroom.

These cabins often sleep three to four people and are located in the middle of the ship, with no exterior view of the vessel's surroundings. 

I've stayed in interior staterooms on a Carnival Cruise Line ship and a Disney Cruise Line ship . Aside from different decor styles and a few small touches, this room category is fairly standard across the board. 

When I'm on a cruise, I like to wake up and open my curtains to look at the ocean or the port where the ship is docked , which isn't an option in these inward-looking cabins.

Apart from having no view, interior staterooms are very small. The exact square footage varies but, for reference, the Disn ey Fantasy cruise ship's interior stateroom is 169 square feet and a Royal Caribbean ship's version is around the same size at 164 square feet .

To put those numbers into perspective, standard hotel rooms in the US are, on average, around 330 square feet , almost double the size of the entry-level cruise accommodation.

I want to be able to maneuver around without tripping over luggage, accent furniture, or my own family members. And because of the lack of space in interior staterooms, that's a challenge.

This category is definitely the most economical option, making it ideal for travelers on a budget .

However, if families, especially ones traveling with teens, can swing an alternative, they should steer clear of cramming into an interior stateroom and opt for a category with more space and privacy.

Ocean-view staterooms provide slightly more space but can still feel cramped

The next category up is usually an ocean-view stateroom.

With an outward-facing window, ocean-view staterooms are a solid mid-tier option for travelers who want more space than an interior stateroom offers but don't want to spend extra for a balcony room.

Their exact size and capacity range from ship to ship, but Disney Fantasy's ocean-view staterooms are 204 square feet , and Royal Caribbean's Symphony of the Seas' version is 179 square feet .

Many of these accommodations fit up to five people. If you have more than four family members (yes, infants who are six months and older are part of the headcount), making the jump from an interior stateroom to an ocean-view stateroom is absolutely worth the extra money.

Some cruise lines sell ocean-view rooms as the entry-level category for families of five or more travelers , simply because many interior staterooms can only accommodate a maximum of four guests.

My top pick is balcony staterooms, which offer privacy and plenty of space 

Balcony staterooms, also known as veranda staterooms, are usually the largest accommodation option you can get without concierge service or extras.

I recommend this category to all travelers setting sail in the future for one reason: the private balcony.

You can open your curtains and enjoy the sights outside, similar to the experience of staying in an ocean-view stateroom. But in this room type, you can step out onto a balcony and take in the sounds and smells, too. 

The rooms' sizes and capacities depend on the ship, but balcony staterooms are usually larger than ocean-view staterooms and tend to sleep up to five guests . Even if the rooms' living spaces aren't substantially bigger, they have the added space of the veranda. 

Including the terrace, balcony staterooms on the Disney Fantasy are 246 square feet and are between 214 square feet to 279 square feet on Princess Cruises' fleet.

When my family stayed in a balcony stateroom on a seven-night cruise, we made great use of the outdoor space. On a shorter cruise, where the balcony itself might not get as much use, I would still book this category for my family.

The upgrade was completely worth the price increase, especially because we were traveling with two sets of grandparents .

To make the most of the balcony staterooms, we even turned our individual verandas into one large terrace by having our steward remove the partitions between rooms.
