Using restaurant.com, you can buy gift certificates good at eateries in your destination city, regularly snagging (in my experience) $25 certificates for as little as $5 to $8.The site is awesome, and it works as well for restaurant certificates in your own city and for obtaining gifts for friends.

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.

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.

It's often cheaper to buy a ticket to London and then fly onward within Europe via a regional low cost airline. Last summer, my husband and I bought consolidator tickets to London for $397. From there, we flew EasyJet to Nice for $72. The total cost was $469—much less than flying directly to Nice, plus we enjoyed a stopover in London.

Need a place for a laptop in your hotel room? Take the largest drawer from the bureau and put it upside down on the bed with the drawer front away from you. This creates a perfect-height desk for while you're sitting comfortably on the bed (you can even lean back on pillows), plus there's side space for papers, and the top leans toward you for easy typing or writing.

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.

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.

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 you head to the airport, make a list of all the items in your checked luggage that would be prohibited in your carry-on. If an item (such as a knife for a picnic) makes its way into your purse or daypack during your travels, it should be accounted for when repacking and put into the checked piece to avoid hassles at airport security.

My husband and I create personal cards (like business cards) before we leave home. We put our name, address, phone, and email address on them, as well as a picture of us. How many people have gotten home from a trip, looked at a slip of paper with a name and address, and wondered, Who is this? The picture helps link a name to a face.

If your travels take you to U.S. cities large enough to have museums, zoos, and/or botanical gardens, consider buying a membership in your home city's counterpart. Many have reciprocal privileges with institutions elsewhere. A membership at Chicago's Lincoln Park Zoo, for example, lets you see the National Zoo in Washington, D.C., and zoos in Los Angeles, Des Moines, and Jackson, Mississippi, at no charge.

I use an inexpensive, thumb-size USB flash drive to store medical and insurance contacts, confirmation codes, credit card numbers, addresses, and phone numbers. It fits in a secure zip pocket in my travel purse. If I don't have my laptop, I can insert the flash drive in most hotel or Internet café computers. Some USB flash drives password-protect your data, or you can download a free encryption program.

Most hotels provide cloth shoe mitts but not polish. In a pinch, a dollop of skin cream on a shoe mitt (or even a tissue) can make scuff marks vanish and leave shoes as shiny as if they'd been cleaned by a pro.

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.

When you're shopping for alcohol on any Caribbean island, ask if there's a Kmart nearby. Often the dis- counter is a short distance from the docks where the cruise ships tie up and has an extensive selection at prices lower than the liquor stores on the main drag. While you're there, pick up that extra roll of film or the sunscreen you forgot.

Before setting off on one of my many backpacking excursions, I head to Kinko's to rebind my guidebook. I replace the cover with a plain black or navy one. It costs about $6 and allows me to blend in much better while traveling. People see my new book as a journal, not a travel guide that labels me a tourist.

Everyone knows that duct tape is great for helping out in travel emergencies, but no one wants to lug around a bulky roll of the stuff. By wrapping a few feet onto a pencil or ballpoint pen, you'll get a miniature roll that does not take up much in the way of additional space.

Bring your own linens. They're useful in a million different ways. Obviously a soft cotton pillowcase makes those scratchy airplane pillows bearable, but it can also be used to gather loose items when deplaning. A nice sheet will cover up an ugly bedspread or sofa, and makes a great tablecloth or picnic blanket.

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.

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.

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.

If you're planning to use an ATM abroad, make sure the money you need is in your checking account, because some foreign ATMs don't allow access to savings accounts. And remember to carry your bank's local phone number with you; 800 numbers generally don't work overseas.

An extra contact lens case holds enough toiletries for a short trip. Squeeze a few dabs of toothpaste into one side and perhaps some facial cleanser or moisturizer in the other side. Just the right amount of each will fit for your overnights or weekends away.

When I'm planning a trip, I almost always call the hotel concierge before I arrive, and if my hotel doesn't have one, I call a hotel that does. Recently, I asked for advice on what to see since I only had four days in a new city. I told the concierge what I thought I should try to do, and she said I had too many things packed into four days. She gave me a list of hot spots to visit and places to avoid, and even recommended a florist to call on for fresh flowers. With her help, my trip was far more enjoyable than it would have been otherwise.

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.

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.

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.

I carry bilingual takeout menus when traveling to countries like China, Korea, and Vietnam. When I'm at a restaurant with no menu (or one that I can't read), I give mine to the waiter so he can point to dishes they can prepare. I've learned to pack a few extra menus, as the restaurants often like to keep a copy.

Ziploc now makes extra-large bags with handles. They're nearly two feet by two feet, and although Ziploc advertises them as being good for storage, they're also useful for traveling. Bring one on long shopping excursions and then use it as an extra carry-on for souvenirs on the way home.
