Trip Coach: April 24, 2007

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.

When buying bottled water, look at the bottle cap to see if the seal is still intact. While visiting the Acropolis on a very hot day this summer, I caught a young boy refilling empty water bottles from a tap and recapping them. He was then selling the bottles to thirsty tourists.

During a visit to Mexico City, I was sitting in a plaza near a fountain, watching the locals stroll around in their Sunday best. Nearby, an older gentleman was playing a concertina; his music perfectly framed the scene. I took lots of pictures, but I didn't have a way to capture that music. Now I pack a small tape recorder along with my camera.

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.

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.

Our bags have been stolen twice from inside locked rental cars. Now we travel with a bicycle cable and lock. If we absolutely have to leave our suitcases in the car, I hook them together by the handles and attach the whole thing to the frame of a seat or a secure item in the trunk. Even if thieves manage to get into our car, the cable will make it very difficult for them to make off with the luggage.

Know your PINs! My husband and I left home with very little cash on us, and instead of stopping to get money at the airport, my husband--ever the procrastinator--decided to wait until we got to Cancún to use his ATM card. Guess what? It didn't work in any of the machines. And although he had several credit cards for cash advances, he didn't know the PINs off the top of his head. We charged everything we could during our stay, but most of the markets don't take credit cards. Needless to say, I didn't come home with a lot of souvenirs.

If the zipper on your luggage or your clothing is giving you any trouble, rubbing some lip balm or candle wax onto the teeth should loosen it.

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 renting a car, photograph any damage the car may have before leaving the rental agency; a digital camera records the date and time of each picture. On a recent trip to Argentina, I rented a car with extensive paint damage. When I returned the car, the agency attempted to blame me for the scratches. I showed them my photographs, and they rescinded their accusations.

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!

Want to visit museums with your children without the boredom and tears? Go to the gift shop first and buy postcards of the museum's most famous works. Have your kids treasure hunt for these masterpieces. When you get home the postcards can go right into your trip album.

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.

Tell me I'm not alone: Almost every time I park my car at the airport, I have trouble finding it when I return. (I even reported my car stolen once after searching for hours, only to discover I was in the wrong lot!) I now use my cell phone to leave myself a message as to where I've parked my car.

Carry a twist tie in your wallet. Among other ingenious uses, a twist tie can temporarily replace a lost screw on a pair of glasses. Just peel the paper or plastic off the tie so you have bare wire, insert it where the screw once was, and twist to tighten. Unlike Scotch tape or a safety pin, a twist tie is small enough to remain hidden and strong enough to hold until you're able to replace the screw.

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.

Water-bottle holsters are good for more than holding water. I own several Water Bottle Totes by Outdoor Research (orgear.com). With their Velcro-like straps, I can fasten them anywher--to my belt, camera strap, fanny pack, purse, or airplane seat. I've used them at various times to carry my camera, binoculars, snacks, umbrella, battery-powered fan, flashlight, sunglasses, a windbreaker, and a rain poncho.

Recycle the long plastic bags in which you receive your home-delivered newspapers. Slip your shoes into the bags before packing them in your suitcase.

I never leave home without dental floss. I've used it as a clothesline between tents in Botswana's Okavango Delta and to replace a lost screw for my sunglasses in Malaysia. I even cut off a piece of floss the size of my waist and headed to the night markets in Bangkok. My "tape measure" assured a perfect fit!

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'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.

When my husband and I travel with our children, our luggage is weighed down by diapers, formula, and other necessities. To save space and hassle, we now ship ahead most of those items to our hotel. We also came across a Web site called babiestravellite.com, where we can order supplies and have them shipped anywhere in the world.

My husband cut an old contact lens case in two and uses the halves to carry his medication when we're traveling. He prefers them to regular pillboxes because lens cases are watertight and compact enough to carry inside a shirt pocket.

Spring skiing often means a wild temperature shift from morning to afternoon. If you want the option of removing outer layers or switching to a lighter ski jacket midday, attach the lift ticket to your clothing with a split-ring key ring. You'll be able to move your ticket as the weather warms up.

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.

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.

Destinationcoupons.com supplies free discount coupons for cities all over the United States and the world. Print them out on your home computer and save on hotels, shows, rental cars, restaurants, and many other activities.

If you make a hotel reservation online and then cancel online, print out and save the cancellation confirmation for at least two billing cycles past your trip. After our vacation, I found a "no-show" charge on my credit card for a room that I'd canceled well in advance. Without the confirmation, I had no way to contest the bill.

If you know you'll be cooking while on vacation, bring along small amounts of the spices you need for your favorite recipes. You'll save by not buying large containers of spices.

Sending a flat-rate Priority Mail box costs $8.10, no matter how much it weighs or which state it's going to. After accumulating too much stuff to fit in my suitcase during a trip to Atlanta, I filled a box with laundry, souvenirs, and gifts for my grandchildren, and mailed it to my home address.
