London at a Price That's Right

Bungee cords make versatile travel accessories. They come in handy at the airport for lashing a duffel bag to a wheeled suitcase. They can be hooked together and used as a clothesline for swimsuits, towels, etc. On skiing trips, hook them onto ski boots to create carrying handles. While camping, use them to secure tarps, to suspend a lantern from a nearby tree limb, or to secure items in a canoe. They even hold your pants up if you misplace your belt.

To save space, pack items for travel that you can use in at least two ways. In a pinch, shampoo can double for detergent when washing your clothes (carry the bottle in a Ziploc bag in your suitcase); sandals or flip-flops also function as slippers; and a swimsuit cover-up can serve as a bathrobe.

Many tourist information offices provide discounted same-day booking services for local lodgings. My husband and I discovered this when we accidentally left a midweek gap in our travel plans between my husband's conference hotel and our B&B in Charleston. Instead of adding another night at either location, we stayed at one of the more elegant inns (normally over $200) for $70, courtesy of the Charleston Convention and Visitors Bureau.

After I fell into a stream in Cambodia, my digital camera wouldn't work. Someone suggested leaving the camera in a bag of rice overnight to draw out any condensation. By the next morning, it was dry and working perfectly.

Whenever I'm in a country where drinking or brushing my teeth with the tap water is a risk, I cover the faucet handles in my hotel bathroom with a towel. As a result, I never accidentally turn on the faucet when I'm half asleep.

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 I travel for business, I usually tack on a few extra days to do something active like hike in a nearby national park. I find that by taking two small suitcases instead of a single large one, I stay better organized and less burdened. I keep my business clothes, papers, and laptop in one bag and hiking clothes and gear in another. I leave the suitcase I'm not using at the time in the rental car and easily carry the lightweight case with the equipment and clothes I need into my hotel.

Disposable-camera lenses scratch just like any other lens would. Place a small piece of painter's tape (or another kind that won't stick too much) over the lens to protect it from contact with other items in your purse or backpack during travel.

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.

A shoe organizer hung over the bathroom door is my solution for hotel-room clutter. The compartments are perfect for stashing everything from room keys and travel documents to toiletries and, of course, shoes. The extra storage space came in especially handy on a recent cruise, when we needed all the room we could get in our tiny cabin.

In North American cities with large Chinese communities, choose a family-run Chinese restaurant and ask for the set family meals, usually written in Chinese. They are more authentic than those typically offered to tourists and people who are not Chinese—not to mention a better value. In San Francisco, for example, you can enjoy a five-course meal, which easily feeds a family of four, for less than $20.

Paramedics now look for emergency contact information in victims' mobile phones. Store the word "ICE" (In Case of Emergency) in your address book, along with the name and number of the person you'd like emergency personnel to call on your behalf. (For more than one entry, use ICE1, ICE2, etc.) Tell your friends or family members that you've chosen them as your contacts and make sure they're aware of any medical conditions or allergies that could affect your treatment.

Deli counters in grocery stores are great mealtime alternatives to restaurants or fast-food fare when you're exploring the United States. The food is fresh, there's a big variety (hot and cold), and economically, it's a great break. I recently had a complete hot meal, including beverage, for $3 from a grocery-store deli.

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.

Avoid spills in your Dopp kit. Cut up plastic grocery bags into little squares and place them under the tops of toiletries to prevent leaks. Discard the squares upon arrival, but bring extras for the trip back.

My husband and I travel to out-of-the-way towns where rural roads can be hard to navigate. We use a handheld GPS (Global Positioning System) to mark the spot where we're staying, the main highway turnoffs, and, most important, the turns to unmarked side roads. When we're back-tracking and arrive again at confusing intersections, we whip out our GPS and immediately know which route to take home.

When overseas, I carry a "cheat sheet" that includes exchange rates and metric conversions. Currency conversions are available at oanda.com.

On my first trip to Cancun, I noticed that my hotel room had a damp, musty odor. The next time I went, I brought two plug-in air fresheners: one for the bedroom and one for the bathroom. This helped tremendously. It was a pleasure to walk in and have a fresh-smelling room. Just make sure you have an adapter, if you need one.

Traveling to non-English-speaking countries can be daunting for people with food allergies. Find someone fluent in the local language to write out what you are allergic to, the seriousness of the allergy (we had a friend include the phrase "this could kill me"), and what to do if you fall ill.

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.

If your children are old enough to dress themselves, consider this packing tip: Put each outfit (including socks and underwear) into a Ziploc bag and pack one bag for each day you'll be on vacation. It will save both time and aggravation, and may even prevent items from getting left behind.

While traveling abroad, I've frequently encountered some appallingly bad (and often very funny) English translations of menus. In those cases, I simply offered to clean up the translations in exchange for a meal. This has worked quite a few times.

If you have to save receipts while traveling, purchase a plastic coupon holder to help you keep track of them (it'll also protect them). Label each section of the coupon holder by category (hotel, rental car, gas, food, etc.) or by day of the week. The coupon holders are compact and easily fit into a laptop case, purse, or travel bag.

We like to buy shipboard souvenirs, so we try to choose a ship that's completing its run of an area--that's when merchandise is generally put on sale. Last year, for example, on a sailing in South America, all of the T-shirts, glassware, and rain jackets were 75 percent off.

Before you leave the United States, photocopy receipts for any expensive items you're taking with you. This way, you won't have to argue with customs on the way home about declaring items you didn't buy abroad. (I'm a photographer, and I always bring expensive cameras on vacations.)

Pack a couple of mountaineering carabiners. Clip one through the handle or strap of your bag and secure it to something solid wherever you may be (to a bench in the park or in a train station, to the railing of an overhead compartment on a bus, etc.).The carabiner adds a bit of security, especially if you're snoozing.

To find the perfect destination with airfare that meets your budget, try Travelocity's Dream Maps travel tool (travelocity.com). Select a maximum fare and a type of destination (city, national park, etc.) and the Web site will display a variety of trips matching that description.

A small compass is a great travel aid. Aside from the obvious benefits during country drives or hikes, it's extremely helpful in navigating winding city streets and orienting yourself once you exit a subway station.

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!

On international flights, I used to fumble through my belongings--often having to retrieve them from the overhead bin--after a flight attendant appeared with customs and immigration forms. (I don't know of many people who have their passport's number and date of issue memorized.) Now I write all that info on the bookmark of whatever I plan to read on the long flight so I don't have to dig out my passport. I can fill out the card quickly--giving me more time to loan my pen to all the people who never seem to carry one.
