A Girls' Getaway in Charleston and Savannah

If you can't sleep due to the heat in your non-air-conditioned hotel room, take a cold bottle of water and place it on your pillow, in the crook of your neck. It will cool your whole body down.

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.

Before I visit poorer countries, I pop into a thrift store and pick up some toys, stuffed animals, and an old suitcase or carryall. I try to avoid toys like Easter bunnies or Santas, which could be offensive, and expensive things that might embarrass parents. The contents of my extra bag bring joy to countless kids who have never had a thing.

When you go to a convention or trade show, don't assume that the official prices at recommended hotels are the best you can do. Go to the hotel Web site. I recently got an AARP rate at a major hotel that was 30 percent below the special price offered through the tradeshow sponsors. AAA discounts often work, too.

Try to book the first flight out in the morning, because those planes often arrive at the airport the evening before. You won't have to rely on an incoming plane, which could be delayed or canceled due to bad weather elsewhere, resulting in your own flight being delayed or canceled.

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.

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.

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.

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.

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.

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!

Pay close attention to those newsletters enclosed in your frequent-flier statements. They usually contain special offers and promotions that can earn you double or triple miles if you stay at a certain hotel or eat at a certain restaurant.

Before traveling by taxi in foreign (or even domestic) locations, ask a local (perhaps stopping in shops to question the sales staff) what the approximate taxi fare would be to a particular location. They've always been pleased to help me. In this manner, I can avoid paying the inflated tourist rates!

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.

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!

Rather than risk losing your department-store credit cards and club-membership cards, you should really leave them behind when you go somewhere you won't need them. Your purse or wallet will be lighter and your worries fewer.

I find that hotel bathrooms rarely have enough hangers and hooks for clothes and wet towels, so I always bring a few snap-lock suction hooks. (They function better than regular suction hooks because they're more secure and are therefore able to hold heavier items.) It's always nice to have a place to hang a bathrobe.

Some people think that traveler's checks aren't necessary anymore, but they really can be useful in a variety of situations. My ATM card wouldn't work on Easter Island, where most restaurants did not accept credit cards and wanted to be paid in pesos. Luckily, our hotel cashed my traveler's checks and gave me the pesos I needed. On Dominica, my purse was stolen. But because I had traveler's checks stashed away in my luggage, the vacation wasn't ruined. I always travel with what I call the "trusty four": American dollars (lots of ones and fives divided up and hidden in several locations), traveler's checks, an ATM card, and a credit card.

My hearing loss once made it impossible to hear any alarm clock. Then I found the Shake Awake, an alarm clock that vibrates. I no longer stare at the ceiling all night prior to an early flight in fear of oversleeping. I clip Shake Awake to my pillow or place it on a hard surface near my bed, where its rattling definitely gets my attention.

When traveling with my kids, I bring a Ziploc bag that includes four things: Benadryl, children's ibuprofen, one of those little medicine cups, and a thermometer. This all-purpose kit will help with minor ailments, or treat a more serious flu until you can get to a doctor. Best of all, it saves Dad from driving around at 2 a.m. looking for an all-night pharmacy.

Be certain to have enough blank pages in your passport. Someone I know had a terrible time getting per- mission to board a flight from Zambia to South Africa because she didn't have the two blank passport pages required to enter South Africa. Thank goodness my husband had read about the requirement. Before the trip, we sent our passports to the center in Charleston and had extra pages added at no charge.

Instead of packing a complete shaving kit, my husband fills his wide-mouth Nalgene water bottle with items such as razors, spare contact lenses, eyeglasses, toothbrush, and so on. This turned out to be particularly useful on our trip to Costa Rica, where we also took the bottle on our day hikes to volcanoes and the jungle.

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).

Booking condos last minute can yield incredible bargains, and there's a way to maximize savings while minimizing the risk that you won't find a room at all. ("Last minute" generally means a month or less before your stay; seven-day deals usually start on a Saturday.) Buy your plane ticket and book a refundable hotel room you can use in case you can't find that bargain condo. Then, a month or so before your trip, start looking at last-minute sites—lastminutetravel.com, site59.com, etc. If you find a deal, simply get a refund on the hotel room and pay the cancellation fee, if there happens to be one. Using this technique, I found a great beachfront, one-bedroom condo on Maui—and I saved about $300.

Some cruise lines offer discounts on a future sailing if you book it while on a current cruise. Back home, you can transfer the booking to your travel agent and work with them to try to lower the price even further. You'll be able to cancel your booking at no cost if you follow the cruise line's cancellation schedule. This is a great way to get some of your onboard expenses paid for in advance.

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!

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!

I used a well-known travel site to price tickets for a trip to Las Vegas. The flight I wanted was available, but I decided to wait to see if prices would come down. That flight stopped being listed after a week, and the next best flight kept getting more expensive. About five weeks later, I checked prices from a different PC. Whaddya know? The original flight was available, for $50 less than that next-best flight. That same evening I checked again from my PC. The flight I wanted was not available,so I deleted the cookies for the site and tried again. Voilà! The flight I wanted at the price I wanted. Moral of the story: Clean up your cookies—it could save you money!

Choosing a cabin is all about location, location, location. Check the ship's layout online before booking, and opt for a room with passenger floors above and below you. You don't want to try to sleep right under the disco, the casino, or the running track.

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.
