Trip Coach: February 19, 2008

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 I showed them my photographs, and they rescinded their accusations.

We decided to take our bikes on our last Caribbean cruise. It was a little crowded in the cabin, so the steward let us store them down the hall with the wheelchairs. We were last off the ship when we docked in Bermuda, but after five minutes we'd left our fellow passengers in the dust. And in less than fifteen minutes, we were far away from the busy port, enjoying a beautiful, deserted snorkeling beach.

If I plan to travel to several countries that use different currencies, I pack a few cloth change purses: U.S. dollars go into one, British pounds in another, euros in a third, etc. When I'm sightseeing, I carry only the money I need; the purses that I'm not using are locked away in the hotel safe. I avoid fumbling around in shops and mixing up coins that look alike. Plus,I always know exactly how much cash I have.

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.

Instead of bringing one of those bungee cables to hang-dry my delicates and socks, I pack a couple of mini plastic hangers--the ones that bras and panties come on when you buy them. They take up very little room in my luggage and can be thrown away at the end of the trip.

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!

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 booking a rental car online, click on "special offers" or "hot deals" to find the company's current promotional codes. Price your reservation using each code. Also, keep in mind that rates fluctuate according to seasons and slow periods. I managed to save more than $170 on a ten-day rental in Orlando, Fla.,by changing my reservation dates twice and by using different codes.

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!

When my husband and I travel, we take at least three different credit cards. I carry one he doesn't have, he carries one I don't have, and we both bring our primary card. If one of us has our wallet stolen, we can cancel two cards and still have one to use. We each have different ATM cards, too--useful if a machine doesn't honor one of the cards, or if we need more cash than our daily limit allows.

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!

If you're stranded overnight at an airport and receive a "distress rate" voucher, call the hotel of your choice before blindly following the airline's suggestion. You may find that for that discounted rate (or a few bucks more) you can stay in a hotel with a lot more amenities than the one the airline would put you in. After a long, mishap-filled trip, anyone can appreciate a really good mattress, a top-notch restaurant, and an indoor swimming pool.

When I travel to a new city, I check with the local running club to see if there are any events planned during my stay. The entry fee is usually donated to a charity, and I get great exercise, meet locals, and tour a part of the city I may not have known about.

Some international airlines still give passengers a goody bag that includes a toothbrush, an eye mask, and socks for the flight. Keep those socks: They're handy when visiting temples in Thailand, Vietnam, and Cambodia, where you must remove your shoes before entering. I slipped on the socks and my feet stayed both clean and warm!

For our road trip through the English countryside, I printed out a detailed map for every location we wanted to visit from multimap.com. I labeled each map with the day we planned on using it and wrote down the interesting sites and places to eat along the way. I kept them all in a folder and added brochures from the places we saw. It was a great souvenir upon returning home.

My friends and I contribute to a kitty and use that money to pay for group expenses such as taxis and meals. It saves us from having to figure out each person's share at every stop. At the end of the trip, we split what remains.

We all know to avoid drinking tap water in certain countries, but remember to forgo ice cubes, too. I've started bringing along two ice trays, which I fill with bottled water and freeze in my hotel room's mini-fridge.

I unpacked a pair of black slacks recently to find them covered with white fuzz. I didn't have a lint brush handy, so I used the luggage sticker from my bag--the gummy side took the lint right off.

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.

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.

If you get lost on a ship, remember that most share a common layout. The lido-deck buffet restaurant, for example, will almost always be in the back to accommodate comfortable outdoor seating in the least windy part of the ship, while the lounge/theater will be in the front because wind is not a factor (there are no windows).

For the most comprehensive information regarding travel by train or by ship, check out seat61.com. I've found that the site has all sorts of helpful advice for Africa, Asia, Europe, and the Middle East.

Treat yourself to a golf-ball foot massage. During a long flight, or afterward in your hotel room, take off your shoes, put a golf ball on the floor, and roll it under your foot. It's a great stress reliever. Practice a bit before you try it on a plane, so that your ball doesn't go rolling down the cabin, tripping up unsuspecting passengers.

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.

Therm-a-Rest's Compressible Pillow is perfect for the plane. It comes in three sizes, packs smaller and expands bigger than any other pillow, and is machine washable. Whenever I pull mine out of my carry-on, I get jealous stares: People always ask where they can get one. REI sells the pillows for $18 to $25, depending on the size (rei.com).

Play Let's Make a Deal when you're shopping for vacations at travel shows or expos. Go armed with your own research and a credit card.(You're likely to get a better price if you know what the vacation is worth, and if you're willing to buy it on the spot.) I picked two Caribbean cruises and headed to the New York Times Travel Show. After haggling with the competing cruise lines, I was offered the first cruise for $50 less than the best price I'd found online, and they threw in free trip insurance. In the end, I chose the second—$30 off with a free upgrade to a balcony stateroom—and truly got a bargain.

Finding healthy breakfast alternatives at an airport can prove difficult. I always travel with an insulated travel mug. Before leaving home I fill it with a high-protein cereal and then request low-fat milk on the flight.

Internet phone services like Vonage can be programmed to send transcribed voice mails to your email in-box. That way, you can check your home answering machine quickly at an Internet cafe without paying insane roaming fees on your cell. The transcriptions won't always be perfect, but you'll get the gist.

Just before I go through airport security, to save time and to avoid leaving something important behind, I collect all loose items--change, money clip, belt buckle, pens--in a large Ziploc bag. I send the bag through the X-ray machine with the rest of my luggage. After picking it up at the other end, I put the things back in place and either toss the bag or keep it for the return trip.
