From saving on gas to driving with kids, here's your ultimate road trip planner

"Easy Travel” is a 10-part series focusing on how to reduce bumps during vacations, anticipate roadblocks and be ready when things aren’t going your way. If you'd like to contribute to our future reporting and share your experience as a source, you can click here to fill out this quick form .

Ina Daly has spent most of her life on the road.

“My dad was a truck driver and that led me to becoming a truck driver,” she said. “What we do in a day, on a daily job would be like a long road trip to most people.”

With nearly 40 years of driving for freight transportation services provider XPO and numerous industry accolades under her belt, including grand champion at this year’s Arizona Truck Driving Championship , Daly is a pro. She’s also a mom and a grandmother who’s happy to share her experiences to make everyone’s road trips better.

“Some of the things I'm telling you are what we truckers tell our family members,” she said. “I've had a lot of accomplishments in my career and going to the National Truck Driving Championships (this month) is a reward, but the bigger reward is being able to share some things … that have the potential to save lives.”

What to do before a long drive

“Make sure that your vehicle’s road trip ready,” Daly said. ”Really pay close attention to your tires, your coolant, your fan belt.”

She notes tire dealers often offer free inspections to ensure tires are properly inflated and undamaged.

AAA spokesperson Aixa Diaz advises getting the whole car serviced before hitting the road.

“If you're a car person and you can, do that yourself at home, by all means,” she said. Otherwise, she recommends getting the oil changed and battery and tires checked professionally. 

To save time and avoid stress, Diaz also suggests filling up on gas the night before leaving and making hotel reservations well in advance, noting that many hotels allow cancellations without penalty up until the day beforehand. 

What do you need before a road trip?

It’s always good to keep an emergency kit with supplies like first aid, a flashlight and extra batteries, and basic tools in the vehicle.

“You want to make sure that if you do have a tire issue, you have the proper tools and jacks in your vehicle to be able to change it,” Daly said. She said warning signals like reflective triangles can also warn other drivers to steer clear in the event of a breakdown.

For road trips, both she and Diaz recommend shelf-stable snacks like protein bars that won’t melt and plenty of water. “Don't think that a bottle or two for everybody is enough,” Daly said. “You've got to have, you know, five or six bottles for everyone.” 

Diaz also recommends wet wipes, blankets during the winter, and any time-sensitive medication or pet food that might be needed in the event of an extended delay.

“These things ideally wouldn't take up too much room in your trunk but they're just good to have in case of an emergency,” Diaz said. “Just think, ‘If I were stuck for a long time, what would keep me comfortable until I was able to (get) help?’”  

A printed map and a general sense of the route can also help in case there GPS hiccups or a phone dies.  AAA’s free TripTik planner can help travelers plot their trips in advance and find rest stops, lodging, food and gas along the way. And its free Gas Cost Calculator can help locate the cheapest average gas prices for drivers when it’s time to refuel.

What I should know before a road trip?

“Everything can be a distraction in the car – the radio, the kids, etc. But the phone is a big one,” Daly advised. “When you’re driving, that thing should not ever be in your hand.”

More than 3,500 people were killed on U.S. roads in 2021 because of distracted driving, according to the National Highway Traffic Safety Administration . 

Daly also recommends watching out for distracted drivers.

“You can tell a distracted driver by their fluctuating speed,” she warned. “They're drifting in their lane. Their head is looking down instead of focusing on the road. You want to give those people a wide berth.”

How long will a road trip take?

Road trips always take longer than expected because of traffic, construction and other things that arise en route.

Diaz says to expect at least an hour longer than whatever the GPS predicts. Daly recommends leaving at least two hours early.

“You don't want that stressful drive,” Daly said. “You’re hurrying. That lends to bad driving behaviors like tailgating and speeding, which leads to accidents. Don’t put yourself in that situation.”

How many hours a day should you drive on a road trip?

“It just varies so much from person to person, how long they’re comfortable driving,” Diaz said. “We want to err on the side of safety. We want people to be safe on the roads and drive the speed limit and not rush it, but everybody's different.”

Switching out drivers can lighten the load, but no matter who is driving, Daly said, “If you're starting to feel a little, less attentive, maybe a little fatigued, it’s time to take a break.”

What time is best to drive?

“We always recommend, especially during the holidays, leave early in the morning,” Diaz said. “The later you leave in the day, the worse it's going to be because a lot of times during the week … you're going to mix with those commuters on the road.”

“Some people enjoy night driving,” she added. “Once you get to like 8 p.m., 9 p.m. traffic comes down a lot.” 

However, she noted drivers who leave in the evening should watch out for fatigue and plan to drive less than if they started fresh in the morning.

How do you take a good road trip with kids? 

When possible, Daly recommends having a designated passenger to help with kids so the driver can focus on the road.  

Another important thing is to keep seatbelts on the whole way.

“Kids have a tendency to take those off,” Daly said. “Make sure they stay buckled up. I've seen some horrible things out there.”

What do kids need on a road trip?

Entertainment helps pass the time, but it doesn’t have to be digital. There are all sorts of screen-free road trip games . 

Diaz recommends printing a map or list of sites or cities for kids to watch for along the way.

“You know, yell it out or mark it on your sheet,” she said. “Have some crayons in the car with them so they're following along on the trip, and they feel like they're part of it.”

“Point out historical landmarks and scenery; enjoy nature,” Daly echoed. “That's one of the things that we truck drivers love about our jobs is we get to see the country and nature.”

Stop at points of interest every few hours or simply for everyone to stretch their legs.

And for those times when kids are on screens, make sure to pack car chargers.

What is the best way to save gas?

Don’t speed. 

“Fuel economy peaks at around 50 miles per hour on most cars, and then it drops off as the speeds increase,” Diaz said. “You think, ‘OK, if I just go 70, I'm going to get there faster, and it'll be better,’ but essentially, you're just wasting gas at that point." Fuel economy can be increased by as much as 15% by reducing highway speeds by 5 to 10 miles per hour, she said.

Don’t idle unnecessarily either, like at rest stops.

“Your car engine consumes about a quarter to a half a gallon of fuel per hour while it's idling,” she said. “But a warm engine only takes about 10 seconds’ worth of fuel to restart, so if it's safe to do so, just shut off your engine.”

Story continues below.

What happens if my tire blows out?

“When you blow a tire, kaboom, it freaks you out. Do not panic,” Daly said. “Don't slow down abruptly or brake hard or jerk the wheel because that will cause you to lose control and have an accident.”

“Just focus on steering,” she added. “Slow very gradually, off to the side of the road in a safe area, and you won’t have any issue from your blown tire.”

How do you drive around semitrucks?

“Be aware of our needs and limitations,” Daly said. “You know we’re big. We need a lot of space around us. We have big blind spots. … If you can’t see the truck driver’s face in the mirrors of the truck, the truck driver can’t see you.”

She advised against passing on the right. 

“If you have to pass quickly, don’t linger over there. We see people driving over there for the shade (and it) puts us in a very dangerous situation,” she said. “And don’t cut in front of us and then hit your breaks. People don’t like to follow a truck because they can’t see around us, so they pass us and then cut in front of us.”

“It takes away that safety cushion we leave in front of us,” she added. “When you see all that space in front of a truck, that's not for your convenience so that you can pass us and cut into it. That’s for our safety and yours.”

By the same token, she advised fellow drivers to leave plenty of space in front of their own vehicles, so they have enough room to stop quickly in an emergency. If another driver cuts into that space, she suggested, “Take a break. Slow down again. Recreate that space. Bite your tongue and think pure thoughts.”

That last tip may not be so easy.

Trip Generation is the first step in the conventional four-step transportation forecasting process (followed by Destination Choice, Mode Choice, and Route Choice), widely used for forecasting travel demands. It predicts the number of trips originating in or destined for a particular traffic analysis zone.

Every trip has two ends, and we need to know where both of them are. The first part is determining how many trips originate in a zone and the second part is how many trips are destined for a zone. Because land use can be divided into two broad category (residential and non-residential) we have models that are household based and non-household based (e.g. a function of number of jobs or retail activity).

For the residential side of things, trip generation is thought of as a function of the social and economic attributes of households (households and housing units are very similar measures, but sometimes housing units have no households, and sometimes they contain multiple households, clearly housing units are easier to measure, and those are often used instead for models, it is important to be clear which assumption you are using).

At the level of the traffic analysis zone, the language is that of land uses "producing" or attracting trips, where by assumption trips are "produced" by households and "attracted" to non-households. Production and attractions differ from origins and destinations. Trips are produced by households even when they are returning home (that is, when the household is a destination). Again it is important to be clear what assumptions you are using.

People engage in activities, these activities are the "purpose" of the trip. Major activities are home, work, shop, school, eating out, socializing, recreating, and serving passengers (picking up and dropping off). There are numerous other activities that people engage on a less than daily or even weekly basis, such as going to the doctor, banking, etc. Often less frequent categories are dropped and lumped into the catchall "Other".

Every trip has two ends, an origin and a destination. Trips are categorized by purposes , the activity undertaken at a destination location.

Observed trip making from the Twin Cities (2000-2001) Travel Behavior Inventory by Gender

Some observations:

• Men and women behave differently on average, splitting responsibilities within households, and engaging in different activities,
• Most trips are not work trips, though work trips are important because of their peaked nature (and because they tend to be longer in both distance and travel time),
• The vast majority of trips are not people going to (or from) work.

People engage in activities in sequence, and may chain their trips. In the Figure below, the trip-maker is traveling from home to work to shop to eating out and then returning home.

Specifying Models

How do we predict how many trips will be generated by a zone? The number of trips originating from or destined to a purpose in a zone are described by trip rates (a cross-classification by age or demographics is often used) or equations. First, we need to identify what we think the relevant variables are.

The total number of trips leaving or returning to homes in a zone may be described as a function of:

\[T_h = f(housing \text{ }units, household \text{ }size, age, income, accessibility, vehicle \text{ }ownership)\]

Home-End Trips are sometimes functions of:

• Housing Units
• Household Size
• Accessibility
• Vehicle Ownership
• Other Home-Based Elements

At the work-end of work trips, the number of trips generated might be a function as below:

\[T_w=f(jobs(area \text{ }of \text{ } space \text{ } by \text{ } type, occupancy \text{ } rate\]

Work-End Trips are sometimes functions of:

• Area of Workspace
• Occupancy Rate
• Other Job-Related Elements

Similarly shopping trips depend on a number of factors:

\[T_s = f(number \text{ }of \text{ }retail \text{ }workers, type \text{ }of \text{ }retail, area, location, competition)\]

Shop-End Trips are sometimes functions of:

• Number of Retail Workers
• Type of Retail Available
• Area of Retail Available
• Competition
• Other Retail-Related Elements

A forecasting activity conducted by planners or economists, such as one based on the concept of economic base analysis, provides aggregate measures of population and activity growth. Land use forecasting distributes forecast changes in activities across traffic zones.

Estimating Models

Which is more accurate: the data or the average? The problem with averages (or aggregates) is that every individual’s trip-making pattern is different.

To estimate trip generation at the home end, a cross-classification model can be used. This is basically constructing a table where the rows and columns have different attributes, and each cell in the table shows a predicted number of trips, this is generally derived directly from data.

In the example cross-classification model: The dependent variable is trips per person. The independent variables are dwelling type (single or multiple family), household size (1, 2, 3, 4, or 5+ persons per household), and person age.

The figure below shows a typical example of how trips vary by age in both single-family and multi-family residence types.

The figure below shows a moving average.

Non-home-end

The trip generation rates for both “work” and “other” trip ends can be developed using Ordinary Least Squares (OLS) regression (a statistical technique for fitting curves to minimize the sum of squared errors (the difference between predicted and actual value) relating trips to employment by type and population characteristics.

The variables used in estimating trip rates for the work-end are Employment in Offices (\(E_{off}\)), Retail (\(E_{ret}\)), and Other (\(E_{oth}\))

A typical form of the equation can be expressed as:

\[T_{D,k}=a_1E_{off,k}+a_2E_{oth,k}+a_3E_{ret,k}\]

• \(T_{D,k}\) - Person trips attracted per worker in Zone k
• \(E_{off,i}\) - office employment in the ith zone
• \(E_{oth,i}\) - other employment in the ith zone
• \(E_{ret,i}\)- retail employment in the ith zone
• \(a_1,a_2,a_3\) - model coefficients

Normalization

For each trip purpose (e.g. home to work trips), the number of trips originating at home must equal the number of trips destined for work. Two distinct models may give two results. There are several techniques for dealing with this problem. One can either assume one model is correct and adjust the other, or split the difference.

It is necessary to ensure that the total number of trip origins equals the total number of trip destinations, since each trip interchange by definition must have two trip ends.

The rates developed for the home end are assumed to be most accurate,

The basic equation for normalization:

\[T'_{D,j}=T_{D,j} \dfrac{ \displaystyle \sum{i=1}^I T_{O,i}}{\displaystyle \sum{j=1}^J T_{TD,j}}\]

Sample Problems

Planners have estimated the following models for the AM Peak Hour

\(T_{O,i}=1.5*H_i\)

\(T_{D,j}=(1.5*E_{off,j})+(1*E_{oth,j})+(0.5*E_{ret,j})\)

\(T_{O,i}\) = Person Trips Originating in Zone \(i\)

\(T_{D,j}\) = Person Trips Destined for Zone \(j\)

\(H_i\) = Number of Households in Zone \(i\)

You are also given the following data

A. What are the number of person trips originating in and destined for each city?

B. Normalize the number of person trips so that the number of person trip origins = the number of person trip destinations. Assume the model for person trip origins is more accurate.

Solution to Trip Generation Problem Part A

\[T'_{D,j}=T_{D,j} \dfrac{ \displaystyle \sum{i=1}^I T_{O,i}}{\displaystyle \sum{j=1}^J T_{TD,j}}=>T_{D,j} \dfrac{37500}{36750}=T_{D,j}*1.0204\]

Solution to Trip Generation Problem Part B

Modelers have estimated that the number of trips leaving Rivertown (\(T_O\)) is a function of the number of households (H) and the number of jobs (J), and the number of trips arriving in Marcytown (\(T_D\)) is also a function of the number of households and number of jobs.

\(T_O=1H+0.1J;R^2=0.9\)

\(T_D=0.1H+1J;R^2=0.5\)

Assuming all trips originate in Rivertown and are destined for Marcytown and:

Rivertown: 30000 H, 5000 J

Marcytown: 6000 H, 29000 J

Determine the number of trips originating in Rivertown and the number destined for Marcytown according to the model.

Which number of origins or destinations is more accurate? Why?

T_Rivertown =T_O ; T_O= 1(30000) + 0.1(5000) = 30500 trips

T_(MarcyTown)=T_D ; T_D= 0.1(6000) + 1(29000) = 29600 trips

Origins(T_{Rivertown}) because of the goodness of fit measure of the Statistical model (R^2=0.9).

Modelers have estimated that in the AM peak hour, the number of trip origins (T_O) is a function of the number of households (H) and the number of jobs (J), and the number of trip destinations (T_D) is also a function of the number of households and number of jobs.

\(T_O=1.0H+0.1J;R^2=0.9\)

Suburbia: 30000 H, 5000 J

Urbia: 6000 H, 29000 J

1) Determine the number of trips originating in and destined for Suburbia and for Urbia according to the model.

2) Does this result make sense? Normalize the result to improve its accuracy and sensibility?

• \(T_{O,i}\) - Person trips originating in Zone i
• \(T_{D,j}\) - Person Trips destined for Zone j
• \(T_{O,i'}\) - Normalized Person trips originating in Zone i
• \(T_{D,j'}\) - Normalized Person Trips destined for Zone j
• \(T_h\) - Person trips generated at home end (typically morning origins, afternoon destinations)
• \(T_w\) - Person trips generated at work end (typically afternoon origins, morning destinations)
• \(T_s\) - Person trips generated at shop end
• \(H_i\) - Number of Households in Zone i
• \(E_{off,k}\) - office employment in Zone k
• \(E_{ret,k}\) - retail employment in Zone k
• \(E_{oth,k}\) - other employment in Zone k
• \(B_n\) - model coefficients

Trains Are Easy To Navigate, Be Careful Not To Lose Your Luggage, And More Things That Both Delighted And Surprised Me About Traveling To Italy

L ast month, my boyfriend and i traveled to italy for a wedding. luckily, i had already visited italy with my family during high school, so this was my second visit to the country., i was around 14 when my family and i traveled on our nine-day trip to rome, florence, and a few other cities. there is something to say about traveling at a younger age with your family and them handling all the planning and logistics of the trip..

I n the past, I would simply go with the flow and never really thought about how we ended up at our destination. During that family trip to Italy, we relied on a tour group to handle a lot of the planning. However, when it came time to plan my own trip to Italy, I felt overwhelmed. Despite this, we managed to plan the entire trip on our own.

We were invited to a friend's wedding in Florence in early September and knew we wanted to extend the trip to be able to travel elsewhere in Italy. Although I had ample time to plan, I procrastinated and planned just about everything pretty last minute for an out-of-the-country trip.

We decided that we wanted to explore a beach town in italy (something that had a different feel from a populated city like florence). the island of ischia — which is off the coast of naples, not far from amalfi coast — was recommended to me by a travel agent friend, so we decided on that., overall, our trip was amazing and i cannot wait to go back to italy — or another part of europe. the experience taught me a lot, and i would love to share some of my takeaways whether you're looking for inspiration for your next trip or just have a passion for travel., 1. english is spoken in some parts of italy more than others., although english is the second-most spoken language in italy, that doesn't mean you'll find all italian citizens speaking it fluently..

After attending a wedding in Florence, we headed to the underrated, beautiful island of Ischia. Although it's not as popular as nearby islands like Capri and Amalfi Coast, it's equally stunning. 

During our stay in Sant' Angelo, a quiet, small fisherman's village in Ischia, my boyfriend and I had to rely heavily on Google Translate to communicate. Living like a local was a wonderful experience, as we were not surrounded by American tourists all the time. However, there were instances where it was difficult to communicate certain things, especially my boyfriend's nut allergy when we were out at a restaurant. 

Most people assumed that we spoke Italian, so we had to quickly type out what we were trying to convey on the Google Translate app. It didn't really bother us, but it was one of the disadvantages of traveling to a non-touristy area of a country.

2. Do your research and familiarize yourself with the vibe of the city or village you want to visit before getting there.

It turns out that although ischia isn't a very big island (it's only 18 square miles ), each village offers something a little bit different. upon booking where on the island we would stay, i honestly didn't do a ton of research so it wasn't until we got to sant' angelo and settled in did we find out that it's a very quiet fisherman's village with stunning beaches — but not much nightlife..

Honestly, this was fine for us because it made for the perfect, most relaxing vacation.  Depending on the vibe you're looking for while on your vacation, I recommend doing extensive research first especially if it's in another county .

3. If you're in a city like Florence, it's worth carrying around a reusable water bottle to refill at drinking fountains.

It was particularly useful when walking around in the heat. additionally, in italy, you have to pay for water at restaurants, so waiters do not refill your glass as frequently as they do in america. as a result, i was always left thirsty after our meals., 4. if you purchase a ferry ticket online in italy, you must validate it before boarding., on that note, make sure to give yourself enough time to validate your ticket because the lines get long and those ferries seem to leave right on their scheduled time..

The port in Naples from where our ferry was departing had several other ferries going to popular destinations such as the Amalfi Coast and Capri. As a result, the lines of people waiting to validate their tickets before boarding their respective ferries were quite long.

5. Traveling by train is an easy and quite enjoyable experience.

After boarding the train, a conductor came by to validate our digital ticket (you can also print a hard copy if preferred). despite the crowds, the italian train stations were not as chaotic or confusing as i had anticipated., 6. utilize public transportation to save some money., 7. compare the prices of an airbnb versus a hotel., 8. wear (or bring) something that covers your shoulders and knees in churches., 9. if you're traveling in italy using multiple modes of transportation, add unique identifiers to your luggage to easily differentiate it., when my boyfriend got off the train in a hurry, he mistakenly grabbed a black hard-shell suitcase that looked similar to his black away bag. since he hadn't put anything to distinguish his bag, he ended up taking someone else's bag, and they took his..

To cut a long story short, to swap the luggage, it turned out to be quite the adventure, that we now call "luggage gate." The lesson we learned here is to always put something on your luggage that makes it stand out from similar-looking bags.

10. It's helpful to carry extra euros for situations where cash is needed.

To avoid paying hefty conversion fees at an international atm, i recommend you order euros from your local bank a few weeks before your trip. most banks don't have euros on hand, so you'll need to call or visit the bank and ask a teller to order them for you. the euros will be delivered to your home once they arrive. unfortunately, i didn't know this and had to pay conversion fees at the airport in rome., 11. a typical breakfast in italy is very different from an american breakfast., 12. small shops close during the day at lunch and will reopen later in the afternoon — or in our experience, not reopen at all., unfortunately, every time i went back to it to shop, it was either closed for a long lunch break or it was just completely closed, we asked our airbnb host (who also owned her own boutique in the village we were staying in) and she said for the most part, shop owners make up their own hours of operation. i was kicking myself for not knowing this sooner because i just assumed the boutique i wanted to shop in would of course be open the next day at the same time., 13. there's so much more to italian cuisine than just pizza and pasta., have you been to italy what regions did you love the most what tips would you give to others planning a trip share it all with me in the comments below.

Miami dolphins | hyde10: good early schedule for rehabbing dolphins; tough finish will again decide season, what happened to home 1 p.m. games easy call on revenge game; best fans’ road trip.

2. Bold prediction:  The Dolphins start 4-1 . Why? Because the opening stretch of five games before the bye week couldn’t be much better for the Dolphins. Here’s how it looks: Jacksonville, Buffalo, at Seattle, Tennessee and at New England. Remember the Dolphins are expected to be without some rehabilitating players like Jaelan Phillips and Bradley Chubb early on so having a softer start helps them in that regard. For that matter, Weeks 1-12 schedule is the second easiest in the NFL based on Vegas win projections. Again, that’s a help for the rehab situation. In the opening five games, Buffalo is always a tough game because Josh Allen must remember the Dolphins didn’t want to draft him. Seattle is tough because it’s a long trip. But between Jacksonville being an annual disappointment and Tennessee and New England being in the midst of rebuilding jobs this is about as friendly a five games as you could draw up. It’s the fifth-easiest start of the opening five games using Vegas’s win projections for teams (the Jets have the easiest; New England is at 30th — meaning the Pats will disappear from view early on.

3. The closing stretch again will decide the Dolphins season, especially if the who-knows Jets are any good. But, again, the Dolphins should be getting some key players back by then. Look at this closing stretch at Green Bay, Jets at home, at Houston, San Francisco at home, at Cleveland and at the Jets. Houston looks ready to contend if it can survive living with success. San Francisco looks again like a NFC contender. Cold-weather night games at Cleveland on Dec. 27 and at the Jets on Jan. 5 means that December/January again will answer a lot of questions.

4. Who wants a bye week in Week 6? Then again, New England has it at the other end in Week 14. Buffalo and the New York Jets have the properly placed one in Week 12.

5. Best fans’ road trip of the schedule: At New England. The shame is the Green Bay game is on Thanksgiving night considering that’s the No. 1 trip for any NFL purist to make. But scratch that trip for most people because of the timing. And I’ll throw out Seattle unless you’ve got a very long weekend because of the travel time. New England? You’ll get some fall weather on Oct. 6, get a good visit to Boston and get to see New England fans grow irate over their team’s slow start as they disappear from view for the next decade.

6. How the mighty have fallen: New England has one prime-time game, the bare minimum the NFL demands. The Dolphins have five. The Jets have five in the first 11 weeks (TV execs betting Aaron Rodgers stays healthy early) and six overall.

7. The Dolphins are tied for 24th for strength of schedule based on last year’s opponent win percentage. That’s the way most strength-of-schedule is measured in the off-season. The more accurate way is based on Vegas’s win projections for teams, as analyst Warren Sharp does it. That gives the Dolphins the eighth-easiest schedule behind Atlanta, Los Angeles Chargers, Chicago, New York Jets, New Orleans, Cincinnati and Indianapolis. The good news: Lots of AFC teams have tough schedules. The five toughest schedules are Pittsburgh, New England, Cleveland, Minnesota and Baltimore.

8. Quick hits:

*The Dolphins are scheduled to face just one rookie quarterback and that’s assuming Drake Maye wins the New England job. They first would face him Week 5. Rookie QBs are 36-76 over the last decade in the first five weeks.

*The Jets could face three rookie quarterbacks who would be playing on the road in their first five games. In fact, from weeks two through five, the Jets face Tennessee’s Will Levis, New England’s Maye (or Jacoby Brissett), Denver’s Bo Nix (or Jarrett Stidham) and Minnesota’s J.J. McCarthy (or Sam Arnold).

Fun fact: The Dolphins haven’t finished with back-to-back games on the road since 2008 when they won the AFC East. Both games were in cold-weather sites (Kansas City and the Jets) just like this year.

9. Revenge Game of the Year: Easy one. Tennessee comes to Hard Rock Stadium again on Monday  night. Last year the Dolphins had a two-touchdown lead with three minutes left and lost. That’s the game you can point to as the one that cost them home-field advantage (losing three straight to close the year didn’t help). Everyone will be tired of hearing about that last Titans game by kickoff this year.

10. Way-too-early Prediction: Dolphins finish 11-6.

All the looks Meghan Markle wore on her trip to Nigeria, ranked

• Prince Harry and Meghan Markle visited Nigeria over the weekend. 
• Meghan wore a variety of ensembles throughout the trip.
• Her best looks from the tour were colorful dresses.

Prince Harry and Meghan Markle just wrapped up a trip to Nigeria.

The Duke and Duchess of Sussex spent several days in the country, which is interested in hosting the Invictus Games, according to CBS News . The Invictus Games celebrated 10 years since its founding on Wednesday.

Meghan wore an assortment of quietly luxurious outfits during the tour, many of them brightly colored.

Take a look at the looks Meghan wore in Nigeria, ranked from least to most stylish.

Meghan's white dress for a Nigeria Unconquered reception had a simple silhouette.

Meghan attended the reception in a St. Agni column dress , available for preorder at $409.

The dress featured a strapless neckline, and it subtly hugged her figure before flowing to the floor.

She also accessorized the look with a cross pendant that originally belonged to Princess Diana, as People reported .

The Duchess of Sussex popped in yellow for a visit to the State Governor House in Lagos.

Meghan rewore the Carolina Herrera dress she donned in the photo she and Prince Harry used to announce her pregnancy with Lilibet in 2021.

The sleeveless column dress featured a high neckline, and it draped loosely around the duchess.

Meghan's dress for a charity polo match featured a subtle, sparkly pattern.

Johanna Oritz's Summer Counts Dress , a $1,995 piece that's now sold out, had a hint of glamour thanks to the coordinating scarf that could be added to its halter neckline. Meghan wore it draped over her shoulders.

The floor-length dress was covered in a floral pattern and featured a plunging neckline and ruching at the waist.

Meghan added oversized Heidi Merrick sunglasses to the look.

She opted for a tailored pantsuit to visit the Defence Headquarters in Abuja, Nigeria.

Altuzarra designed Meghan's white suit, which featured a blazer with a single button and wide-legged pants.

She paired the suit with a white top, gold pumps, and gold jewelry, as well as a floral corsage.

The peach dress Meghan wore to visit Lightway Academy stood out with architectural detailing.

Heidi Merrick has become a go-to designer for Meghan, so it's no surprise she chose the brand's blush Windsor Gown for the Nigeria tour.

The maxi dress has a high neckline and cinches at both the waist and thigh, creating a casual take on a dropped waist. The back features cutouts on the sides and in the center of the dress, giving it a modern edge.

The sold-out dress retails for $1,350 and has a similar feel to other quiet luxury looks Meghan has worn recently.

She attended a basketball game in Lagos wearing a traditional Nigerian skirt.

Meghan's Nigerian skirt was the star of her outfit, with a blue striped pattern and a tie fastened at her waist. The skirt was gifted to her during her trip, according to People .

She paired the skirt with a Carolina Herrera blouse with the sleeves folded up, gold Burberry pumps, and Heidi Merrick sunglasses.

The look was both casual and sophisticated.

Meghan's dress for a volleyball match had a subtle cutout and a daring slit.

The Duchess of Sussex arrived at the match in a $2,850 Johanna Oritz dress.

A dark-green leafy pattern covered the dress, which had a sweetheart neckline and hit Meghan at the ankle. A diamond-shaped cutout sat in the center of the bodice, framed by textured spaghetti straps.

A thigh-high slit completed the beachy feel of the dress, which Meghan wore with Heidi Merrick sunglasses and black Emme Parsons sandals.

Ruffles on the hem of Meghan's red dress for a Women in Leadership panel made it stand out.

Meghan's $275 midi dress was made by Orire, a Nigerian designer.

The red garment's scooped neckline featured spaghetti straps and a slightly cinched waist.

The hem of the dress was lined with large ruffles, adding a touch of glamour to the simple silhouette. Nude heels from Aquazzura completed the look.

According to InStyle , Meghan said during the panel that she donned the colorful dress at the encouragement of people she met in Nigeria.

"I am just flattered and honored and inspired," she said. "It has been a whirlwind 24 hours since we arrived, and I very quickly got the memo that I need to wear more color so I can fit in with all of you in your incredible fashion!"
