Making international calls back to the States can be confusing if you're using a calling card and you're dialing a number by its catchphrase, such as CALL ATT. Obviously, many countries don't have the English alphabet on the telephone keypad. My solution? I create my own small keypads on a computer, print them out, and attach them inside my wallet, to my passport, and to my calling cards.

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.

If you take an overnight flight to Europe and early check-in at your hotel isn't an option, ask the concierge if you can store your luggage until later in the day and use the hotel gym's shower. You'll be refreshed and ready for sightseeing. Pack toiletries and a change of clothes in your carry-on.

Put an address label on your one-time-use camera. At a Final Four game in Indianapolis, we exchanged identical Kodak Fun Savers with another traveler so that we could take souvenir photos of each other with our respective cameras. But afterward, we couldn't tell whose camera was whose. Luckily, I remembered how many exposures remained on mine, so we got ours back. Next time, I'll just label it.

Pack a glue stick for journaling. Rather than bringing home an envelope full of ticket stubs and mementos, you can glue them into your journal as you're traveling. You'll have a better chance of remembering what the ticket was for if you label it right away.

Many computer photo albums use camera date stamps to organize collections. Whenever you're traveling in a time zone that might affect the date stamp (if you're crossing the International Date Line, for example), remember to reset your camera's clock.

I've discovered a wonderful way to enjoy massages at a fraction of the usual cost. Some massage-training schools provide superb service in a spa-type environment. Do a Google search to see if there are training programs near your next vacation destination.

Carry a Polaroid camera when traveling to developing countries. In Cambodia, several village children gathered around us, posed enthusiastically for pictures, and were fascinated by their images in our digital camera. We wanted to send them the pictures, but they were unable to tell us their address. Polaroids would have solved the problem!

Don't assume you can save a spot at the pool with your towel. Cruise lines give you one pool towel at the start of the cruise. If you don't have it (or a cleaned trade-in) at the end, you'll get charged. If you let it out of your sight, you run the risk of losing it or having it stolen by a fellow cruiser.

Driving around Italy last summer, my husband and I found that even the most detailed maps left us scratching our heads in confusion. Desperate and lost, we decided to follow a tour bus. Guess what? It got us exactly where we wanted to go.

After I fell into a stream in Cambodia, my digital camera wouldn't work. Someone suggested leaving the camera in a bag of rice overnight to draw out any condensation. By the next morning, it was dry and working perfectly.

I always have problems locating my rental car in a large parking lot. Now I bring along a brightly colored bandanna and tie it to the antenna.

A simple but effective anti-pickpocketing measure is to fasten a safety pin across the opening of the pants pocket on the inside. Leave enough room to pull your wallet out with some effort, but not enough for a quick hand to lift it in a second or two.

Lightweight, washable, and multifunctional, a cotton sarong is an easy and practical addition to every traveler's don't-leave-home-without-it bag! I've used mine as a swimsuit cover-up, as a picnic blanket on the grounds of a château in the Loire Valley, as a temporary skirt (over my shorts) in a Bangkok temple, and as an extra pillow while hiking the South Rim of the Grand Canyon. It's also handy as an airplane blanket, emergency towel, or tablecloth.

Before booking your next ski trip or reserving a table for dinner, find out what your credit card company has to offer. American Express sometimes has discounts on lift tickets; MasterCard has offered buy-one-get-one-free at local restaurants; and Discover Card has access to deals to Universal Studios. Check out americanexpress.com/offerzone, mastercard.com (be sure to click on Promotions), and discovercard.com.

If you're looking for authentic street food--whether you're in New York or Bangkok--don't buy from the pitifully lonely vendor who has no customers. Head to the cart with the longest line of hungry people in front of it. Locals know which vendors serve the best (and safest) food. Even if you have to wait, your stomach will thank you.

On my first trip to Cancun, I noticed that my hotel room had a damp, musty odor. The next time I went, I brought two plug-in air fresheners: one for the bedroom and one for the bathroom. This helped tremendously. It was a pleasure to walk in and have a fresh-smelling room. Just make sure you have an adapter, if you need one.

Many tourist information offices provide discounted same-day booking services for local lodgings. My husband and I discovered this when we accidentally left a midweek gap in our travel plans between my husband's conference hotel and our B&B in Charleston. Instead of adding another night at either location, we stayed at one of the more elegant inns (normally over $200) for $70, courtesy of the Charleston Convention and Visitors Bureau.

When you change your clocks back or forward, be sure to check the expiration date on all your frequent-flier miles. This way they're checked twice a year. We overlooked one of the many accounts in our household and lost a free ticket when the miles expired.

Before my last long flight, I went to librivox.org and chose a bunch of books, short stories, and poems to download to my iPod--for free. The site has both adult and children's books, and the list is growing. All of the titles are in the public domain, and they're read by volunteers, so there's no question of copyright infringement. Even if you don't own an iPod, you can download them to your computer and burn them onto a CD.

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.

Baby wipes aren't just for babies. Slip a travel-size pack into your carry-on bag and use the wipes to kill germs on public toilet seats and in phone booths. In a pinch, they can also remove stubborn stains from clothing.

If your vacation spot is a major port of call for cruise ships, plan excursions for the days that the ships aren't docked. Tours will be less crowded, and you'll get to see and do a lot more.

When I travel with friends, we decide ahead of time who's going to bring what. If we're sharing a suite or have adjoining rooms, we don't need multiple hair dryers and umpteen bottles of shampoo. With the weight limits on baggage, we'll need the extra space in our suitcases for souvenirs!

I always pack a Petzl Tikka Plus headlamp. It's small, weighs next to nothing, and is perfect for reading in bed at night without disturbing my husband. They're sold online and at outdoor-gear stores for about $33.

When not taking pictures, keep your memory card away from your camera. It's a simple method to ensure that any photographs you've shot will be safe even if your camera is stolen. My husband and I learned this lesson the hard way when we lost 250 shots of Kauai.

I teach a Tulane University seminar on independent European travel for first-timers. Until recently, I advocated Europe's great rail networks as the way to go. Now, with the plethora of budget airlines, I recommend a combination of the two. But it makes the planning stage—which I find almost as much fun as actually taking the trip—more involved. Thank goodness for whichbudget.com, a Web site that lists, by city, which budget airlines serve which cities. Then, to find links to all of Europe's state railway Web sites, visit railfaneurope.net. Each site generally features a travel planner and, almost invariably, an English-language option.

Even if you're staying at a standard resort hotel, take advantage of the day passes sold by many all-inclusive resorts (i.e., the right to use their facilities--such as swimming pools and beach chairs--and enjoy their meals for a day). The passes are primarily designed for cruise passengers on day trips but can be obtained by anyone for very little money. For persons staying in a less-expensive, no-frills hotel, it can give you the experience of a larger, more extensive resort for a day or two.

Even if you're not hungry when the flight attendant comes around with the snack service, take it for later. Although peanuts may not look appetizing at 7 a.m., they will look good later if you have nothing better to eat. And it saves you from picking up something at expensive airport shops.

My husband and I always travel around Europe by train. When we arrive in any city, we first stop at a ticket window and get all the information we'll need for the next leg of our journey. This gives us plenty of time to find an English-speaking ticket agent who'll print out departure times and platform numbers for us. Before leaving the station, we can note the location of the platform we'll be looking for that morning. One wrong move when you're rushing for a train and you could end up in the wrong city!
