Walk the Walk: The Appalachian Trail

Most cruise lines offer certain drinks for free--juice, lemonade, iced tea, coffee, milk, tea-but you'll have to pay for soda. If you're a caffeine addict, pack a bottle or two. Unlike on a plane, you won't have to worry about paying for the added weight.

Pack light, or that great deal you found on airfare won't seem that great. On a Ryanair flight between Glasgow and Dublin, my husband and I were charged over $100 for excess baggage weight (the airline tickets themselves cost less than half that). Be sure to check the weight limits—especially on low-fare airlines—before you leave home.

Place a coin over the veins on the inside of your wrist (about two finger widths from the base of your palm) and secure it in place with a rubber band or ponytail holder. The gentle pressure of the coin will stimulate nerves that control nausea, just like the motion-sickness bands that are sold at drugstores.

Grab-rails and nonskid surfaces aren't common in European bathtubs and showers. I pack a few decorative rubber pads that have non-adhesive suction cups, so I can use them when needed to prevent a slip or fall, and then I take them with me to the next hotel.

I was booking tickets online for an upcoming flight to Europe from the East Coast. One particularly attractive fare was offered on a U.S. airline as well as on its foreign "partner airline." Same plane, same flight, same base price. But it was more than $100 cheaper per ticket to book with the foreign airline versus the U.S.one. We saved more than $400 for four tickets, but we'll be on the same plane!

My husband packs Q-tips in a plastic cassette case. It's small and snaps shut, keeping the cotton swabs clean and dry.

If you start to feel a painful blister coming on, put some lip balm or Vaseline on the hot spot--it'll help stop the rubbing.

Anyone tired of the same boring postcards that are found at every roadside tourist trap should try shopping for vintage postcards at an antiques shop. They're a great addition to any photo album, as they often show what the local attractions looked like prior to development.

If your flight is canceled, don't just wait patiently in line to be booked on another flight; call the airline's 800 number. They'll answer your call faster, and you won't be waiting with other stranded passengers from that flight. (Or cover all bases by calling while in line.)

I travel with a mailing tube in my suitcase because I often buy paintings, drawings, and maps. My souvenirs always arrive home safe and sound. I just leave the mailing tube in my suitcase until the next trip.

Pack a travel-size shampoo container refilled with detergent and a one-gallon Ziploc bag for when you need to wash hosiery, bras, and other delicate undergarments. Put a few drops of detergent into the bag and fill it part way with water. Place the garment in the bag, close it up, and shake it around for a few minutes. Instant washing machine! For larger pieces of clothing, I've used the plastic laundry bags supplied at most hotels. Just hold on to the open end tightly.

It's unnecessary to make a packing list for each trip. Instead, draw up a master list with everything you might need on any given trip--from ski goggles to snorkels, slippers to saline solution. Save it on your computer. Before you start packing, cross out anything you don't need for that particular trip.

By the time I got home from my first trip to Europe in 1963, I'd collected menus from several restaurants I liked. I threw them into a box. In 1988, I returned to Europe and went to the Middle East. Once again, I picked up a few menus. This time I had them all framed and they now hang in my kitchen. Since then, I've added to the collection. It's fun looking at the prices and remembering the good times—plus they make great conversation pieces when I have a party.

I'm a gadget freak, and I don't like to travel without things like my digital camera and iPod. On one trip, though, I put my camera down in a crowded restaurant and then forgot to put it back in my bag. By the time I remembered it, the camera was long gone. Now, I attach those kinds of items to my daypack with a lanyard. They're still easy to pull out and use, and they never get left behind.

Check out grocery stores in Europe for bargains on wine. On our last trip to Italy, I found a 1993 Banfi Brunello in a small market for $16. If I could find it at all in my local wine shop, that same bottle would cost more than $100. I only wish I had listened to my husband and bought all three of the bottles the store had.

When planning a vacation, we send away for brochures from major tour operators. They provide hotel and restaurant recommendations and sightseeing itineraries, which we then duplicate on our own. Use this trick to mimic the vacation packages of high-end tour operators for what can turn out to be a fraction of the cost.

When I'm on the road, I often have to use the hotel iron before heading out to business meetings. But getting water into the iron can be a hassle--most irons won't fit under the sink faucet, and using a glass to pour water into the tiny hole is nearly impossible without spilling everywhere. There's an easy solution: Use the carafe from the coffee maker. Just be sure the carafe is clean, or you could end up with coffee stains on your clothes.

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.

Whenever my husband and I get new pairs of eyeglasses, we relegate the old ones to our luggage, along with an inexpensive repair kit from the drugstore. If something happens while we're away from home, we can hopefully fix the glasses ourselves. If they're beyond saving, we have the backup pairs to get us through the rest of the trip.

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.

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.

If you're a woman traveling alone, or your accommodations don't inspire confidence, simply wedge a small rubber doorstop at the base of the door when you're inside the room. It'll be virtually impossible to open the door from the outside.

A beach ball can replace many expensive in-flight gadgets. Depending on how much you inflate it, the ball can function as a very comfortable footrest, a back support, or a lap pillow to support your book.

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.

If you're packing a lunch to eat later in the day, freeze a 16-ounce water bottle and pack it, along with yogurt, cottage cheese, a ham sandwich, or whatever in a light- weight, insulated bag. Your snacks will remain cold, and you can drink the water.

Create your own postcards by writing on the back of photographs that you've taken and developed while still on your trip.

Before you buy expensive bottled water from your hotel room minibar, head to the fitness center. You'll be able to fill up an empty bottle at the gym's water cooler or fountain for free, and you don't need to break a sweat.

You won't always save by bringing the rental car back early. Alamo has an early-return policy at all of its locations, designed to discourage customers from returning cars early. If you show up at the lot a day or two ahead of schedule, Alamo will recalculate what you owe them at the daily rate; if it turns out to be less than what you would have paid for the week, they'll charge a $15 fee. Yet another reason to read the fine print on your contract carefully!

If you arrive in a foreign city after banking hours (and you can't use an ATM), convert only the money you'll need for the night. Some exchange booths offer a less favorable rate after banks close and then switch back to competitive rates when banks reopen.

When carrying around my small umbrella, I put it in a Ziploc bag. After using it, I can store the umbrella, back inside the Ziploc, in my shoulder bag without getting everything else soaked.
