Secret Hotels of the Caribbean: Jamaica, Bahamas, and More

If you even manage to get a cell signal while at sea, your roaming charges will be outrageous. To communicate with your cabinmates, leave Post-it Notes on your door detailing where you'll be throughout the day.

Save the flip-flops you're given at the nail salon after a pedicure. They make great shower shoes. They're lightweight and dry quickly, and you can throw them away at the end of your trip.

Before traveling to any city, do a search on the Internet of the city name and the word "coupon" ("New Orleans coupon"). You will find many sites offering two-for-one, percentage-off, and dollar-off discounts. On a recent trip to St.Louis, we saved $100 at restaurants and attractions.

Remember to check the hours of operation for your hotel's airport shuttle. In Rome,we were surprised to learn that our hotel--which touted its shuttle--only offered the service a few hours a day.

We're active travelers but find guided bike tours from companies like Backroads too expensive. Our advice: After rolling into town, ask at a bike shop for the best routes. Better yet, call or e-mail before you leave home (search the Web). We've found group rides and races this way, and have made a lot of friends. We're instant locals!

Put toys within kids' reach on road trips. Hang a shoe organizer on the back of the passenger seat so children can keep stuffed animals, books, and games organized in the pockets. Having everything close at hand may help prevent meltdowns along the way.

We've noticed that when booking a flight for our family under one reservation, some airlines will only credit the 1,500 bonus miles (500 for booking online, 500 each way for printing boarding passes) to the person whose name the reservation is under. This is regardless of whether the other family members have mileage accounts. To avoid this, make a separate reservation for each of your family members and then pick seats together.

After looking for years for the perfect toiletries bag and being frustrated by many that were less than ideal, I finally discovered one that is just right: a soft-sided lunch box I bought at the supermarket. It has an outer zipped pocket with small compartments and slots perfect for often-used items like a toothbrush and toothpaste. There's a small removable zipper pouch inside (meant for a small ice pack) for those smaller, hard-to-find items like nail files and pill bottles. The remaining space inside is just right for larger items like shampoo and hand lotion. Other helpful features include both a small handle and shoulder strap and a waterproof, easy-to-clean interior. As an elementary school teacher, I know firsthand that it'll last: It was designed to withstand daily use by kids!

In order to keep track of my bags, I use a small metal bell--the kind dancers from India wear on their ankles. I thread it with fishing line and tie it to my carry-on. If anyone touches my bag after I set it down, the bell chimes. It's not a very obtrusive sound, but it's distinctive enough for me to notice if a thief is trying to get into my things. The same bell can be hung on the doorknob inside your hotel room.

Put your perfume and cologne bottles inside pairs of rolled-up socks to keep them cushioned during your journey.

An extra contact lens case holds enough toiletries for a short trip. Squeeze a few dabs of toothpaste into one side and perhaps some facial cleanser or moisturizer in the other side. Just the right amount of each will fit for your overnights or weekends away.

Attach a few carabiners--the kind of clips rock climbers use--to the top of your wheeled suitcase. Purses, cameras, and shopping bags can be clipped to your suitcase, giving your hands and shoulders a rest while you're walking around the airport.

I always try to work out before heading to the airport. It usually gets me tuckered out enough that I can relax and sleep on the plane. If I don't have time for pre-travel exercise, I take a brisk walk through the terminal before boarding or find a quiet spot in an empty gate for a little yoga.

A bike tour will offer a good introduction to a place, and you'll cover much more ground than if you were on foot. In Buenos Aires, for example, Lan & Kramer Bike Tours (biketours.com.ar) has a few guided itineraries that are fun for all ages and abilities.

Save major bucks by going onto eBay and purchasing coupons and gift certificates that others don't want or can't use for lodging, transportation, food, and admissions. I've found great discounts for airline and Amtrak tickets; car rentals; entrance to amusement parks such as SeaWorld, Disney, or Universal Studios; as well as overnights at many hotels. For example, I bought a $30 savings coupon at SeaWorld for only $1. Simply search for your destination and then type in "coupon" or "gift certificate."

I try to avoid checking any luggage, but the airlines are getting stricter every day about the size and weight of carry-ons. So when I pack, I put any important stuff in a plastic bag and place it in a front pocket. If I'm told to check my carry-on when I get to the gate, I can just pull out the smaller bag and board.

Restrooms abroad rarely have hooks on stall doors. Our solution: Pack a small S hook in your shoulder bag and make use of a hole in the wall, a pipe, etc., to hang purses, jackets, or anything else you want to keep off the floor. S hooks can be found in most hardware stores, near the screws and bolts.

We were told by an airport security official to tape a business card onto the cover of our laptop. Turns out he has an average of six laptop computers left behind each day! There are so many more procedures now--removing shoes, removing coats--that people forget when they send their laptop through in a separate bin. The official added that it's very difficult to return them because most laptops have passwords that keep the owners' personal information hidden.

In areas where the majority of people don't speak English, head to an Internet café. In our experience, they're full of friendly young people anxious to practice their English.

Note the expiration dates of any debit or credit cards you plan on using while you're away. In Budapest, I tried to withdraw cash with my ATM card, only to find that it had expired just days before.

The middle seat isn't always awful. On a recent trip overseas, I called too late to confirm an aisle or window seat. After explaining the plane's AB-CDEFG-HI configuration, the customer service agent urged me to take the very middle seat, E, because D and F have less foot room. (In some rows, there are metal boxes underneath the seats in front of you that house wiring for onboard electronics.) I went along with her advice somewhat skeptically, but I ended up with plenty of room. The people on either side of me weren't so lucky.

Once the hotel shampoo bottles I always seem to bring home are empty, I refill them with my own brand of shampoo, conditioner, and shower gel--instead of buying travel-size containers at the drugstore. I toss them, along with other small items (toothbrush, toothpaste, nail file, pillboxes, and a comb), into a medium-size Ziploc bag, and I'm ready to go; the clear plastic lets me find things easily.

I've found that by wedging a bath mat under my hotel-room door, I can reduce any light or noise coming from the hallway—ensuring that I'll sleep better.

If your children are old enough to dress themselves, consider this packing tip: Put each outfit (including socks and underwear) into a Ziploc bag and pack one bag for each day you'll be on vacation. It will save both time and aggravation, and may even prevent items from getting left behind.

There's nothing worse than trying to fall asleep under a mosquito net and then realizing that the bugs are finding a way inside. So next time you're heading someplace tropical--where you know you'll be sleeping under mosquito netting--remember to toss a roll of Scotch tape into your suitcase. It's perfect for quick repairs.

Avoid spills in your Dopp kit. Cut up plastic grocery bags into little squares and place them under the tops of toiletries to prevent leaks. Discard the squares upon arrival, but bring extras for the trip back.

Before leaving on a trip, I print the names and addresses of my friends and family onto clear mailing labels. (All standard word-processing programs have preset templates for creating address labels.) Then, I take the address-label sheets with me on vacation. Since the addresses are already saved in my computer and the mailing labels are adhesive, addressing postcards has become really easy.

It helps to have a calculator if you plan to do a lot of shopping in foreign markets. When you find something you like, hand the seller the calculator and ask him to enter his best price. It's easy to convert the response into dollars so you know what you're spending. If necessary, the calculator can be used to haggle, especially if you don't speak the language.

I started saving the heavy-duty plastic wrappers that sheets and curtains come in. Most have zippers or snaps, great to hold everything from toiletries to shoes to wet swimsuits. And I bet airport security must love them because they're see-through.

Before exchanging foreign currency at the airport, find out if there's a departure tax. At the Bangkok airport, we were very upset- as were travelers around us- to find we had to pay a fee before continuing to our gate. Unfortunately, by that point everyone had cashed in their baht, so the options were a conveniently located ATM, a credit card, or an exchange booth with notably poor rates. When we described this incident to friends, they told us of a similar experience when trying to leave the Dominican Republic.
