What Are the TSA Rules Again?

To ensure the studs of pierced and delicate earrings don't get damaged, I put them in a film canister. An added benefit is that they're less likely to be stolen when left in a suitcase or hotel room, because thieves presume there's nothing inside but film.

Before you go to sleep, check to see if a previous hotel guest left the alarm clock on. I've been awakened before 7 a.m. twice in the last couple of months by alarms I did not set. (Make sure the clock shows the right time, too!)

I always pack a Petzl Tikka Plus headlamp. It's small, weighs next to nothing, and is perfect for reading in bed at night without disturbing my husband. They're sold online and at outdoor-gear stores for about $33.

At a theme park, tie a brightly colored scarf to the handle of your stroller before you enter a ride. When you return, you'll be able to quickly pick out your stroller from a sea of look-alikes.

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 traveling solo and your room has a double bed, sleep on the side farthest from the phone. It's slept on less frequently and is therefore more comfortable.

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.

When my husband and I would stay in a hotel with our two-year-old, a full night's sleep was out of the question. The minute our son opened his eyes (at 2,3,or 4 a.m.), he woke us, thinking it was time to play. We now pack a pop-up tent and set it up in a corner of the hotel room with books, a blanket, and a few small stuffed animals. The tent folds down to a 14-inch circle and weighs about a pound. It works great! My son has his own "room" to sleep in when we vacation, and we all get to sleep through the night!

When my husband and I visit places like India or Thailand, we pack only one extra change of clothes. When we arrive, we hit a local market and buy local attire--woven shirts, saris, sarongs, etc. Not only does this make packing easier, but we get a better cultural experience and end up with lots of wearable souvenirs!

You can enjoy free airport-area parking by staying the night before departure at an airport hotel or motel that offers park-and-fly rates. The cost of that overnight (which usually entitles you to two weeks of parking) is much less than what you'd otherwise pay at an airport parking lot.

Batteries for cameras, laptops, cell phones, and other devices can be charged at night in your hotel room. But if you're doing a lot of driving, you might want to buy an inverter to charge them while on the road. Inverters (which plug into the car's cigarette lighter) are small, inexpensive, and can be purchased at auto-supply, variety, or electronics stores.

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.

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.

If you're even slightly tech savvy and have a cell phone that will work overseas, check with your service provider about the cost of text messages. Some carriers offer free incoming text messages, and several Internet search engines (Yahoo, MSN, etc.) will send free text-message "alerts" to your phone while you're away. Prior to your trip, log on and request that weather forecasts and news updates be sent to your number daily. Even if you never use your phone for costly overseas calls, you can receive up-to-the-minute information, in English, about your hometown or cities on your itinerary.

Shout Wipes take up very little space in your purse or backpack and are invaluable for treating stains. While traveling on an airplane, I gave one to a most grateful Italian after he spilled wine on his tie. Our friendship extended through customs, and we're now e-mail pals. Great stuff!

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.

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.

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.

Don't put your magnetic sunglass clip-ons in the same pocket as your mass transit fare cards or hotel key cards. I managed to erase both my subway pass and my hotel key on a recent trip.

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.

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 visit a country where you don't speak the language, pick up a book of your hotel's matches or one of its business cards; they usually have the hotel's name and address printed on them. Then when you're out sightseeing and want to return to your hotel, show the matchbook or card to the cabdriver if he doesn't speak English.

I like to bring a Frisbee when I travel. At the hotel, it's a convenient place to collect car keys, loose change, my ChapStick, and any other small objects I normally keep in my pockets. I always know where everything is, and things won't fall off the nightstand. It's also handy to have so you can play Frisbee at a nearby park or beach.

When planning a vacation, we send away for brochures from major tour operators. They provide hotel and restaurant recommendations and sightseeing itineraries, which we then duplicate on our own. Use this trick to mimic the vacation packages of high-end tour operators for what can turn out to be a fraction of the cost.

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.

A simple but effective anti-pickpocketing measure is to fasten a safety pin across the opening of the pants pocket on the inside. Leave enough room to pull your wallet out with some effort, but not enough for a quick hand to lift it in a second or two.

In order to keep track of my bags, I use a small metal bell--the kind dancers from India wear on their ankles. I thread it with fishing line and tie it to my carry-on. If anyone touches my bag after I set it down, the bell chimes. It's not a very obtrusive sound, but it's distinctive enough for me to notice if a thief is trying to get into my things. The same bell can be hung on the doorknob inside your hotel room.

Use the shoeshine mitt often found in hotel bath- rooms to store your sunglasses. They fit nicely inside the pouch, and when you take them out, you have a soft material to clean them with. For extra protection while traveling, I store my sunglasses inside the shoe-shine mitt, fold the end closed, and then place it in my glasses case.

A company called Orikaso makes brightly colored polypropylene sheets that can be folded--kind of like origami--to form a dish, bowl, or cup. The sheets are lightweight and reusable, and you simply flatten them when you're finished. We found ours at a sporting goods store, but you can also buy them online. Check orikaso.com for retailers.
