Want to visit museums with your children without the boredom and tears? Go to the gift shop first and buy postcards of the museum's most famous works. Have your kids treasure hunt for these masterpieces. When you get home the postcards can go right into your trip album.

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.

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!

The help of a concierge at an expensive hotel is available even if you're staying at a motel across the street. Go to the concierge with $5 (or whatever the assistance is worth to you) held discreetly but visibly in your hand. Chances are you won't be asked whether you're staying at the hotel. This worked for us once when we were stranded by a blizzard. We tried to rebook our flights on our own, but phones at the airlines were busy for two days straight. The concierge at a fancy hotel a few blocks away got through on his first try and managed to rearrange our flights for us.

With two of our last three car rentals, the local branch wanted documentation beyond the standard insurance card issued by our insurance company. In San Juan, we were delayed a half hour while the agent made phone calls to verify that our liability insurance was good in Puerto Rico. In Miami, if we hadn't provided proof that our insurance covered rental cars, we would've been charged a daily collision insurance fee. Fortunately, we knew ahead of time and took a copy of the pertinent section of our policy. Our credit card included car rental insurance, but proof of that coverage was also required.

Take along an extra duffel bag for your laundry. As your vacation progresses, throw dirty clothes into the duffel, keeping your suitcase for fresh clothes. At the end of the trip, put a tag on the bag and check it at the airport. This will also give you space in your luggage to bring home souvenirs or new clothes.

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!

We always e-mail our itinerary--including flights, hotels, and confirmation numbers--to ourselves and to family members. If our luggage is lost or our wallets are stolen, all of this essential information is just an Internet café and a few quick clicks away.

Many computer photo albums use camera date stamps to organize collections. Whenever you're traveling in a time zone that might affect the date stamp (if you're crossing the International Date Line, for example), remember to reset your camera's clock.

As a flight attendant, I'm always amazed by the stuff that people leave behind. Most of it never gets back to its rightful owner because there's no way of knowing who the owner is. To avoid misplacing your property, put things back into your carry-on after using them--never on the floor or in the seat-back pocket. Label important items like books or games with return address labels so they can be sent back to you if found.

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!

Flight attendants often work vampire hours and have to sleep during the day. How do we keep the sunlight from leaking into our hotel rooms? We clip a skirt hanger (or two) to the middle of the drapes to seal them together.

I live in coastal Florida, where the electricity sometimes goes out during violent storms. Before a trip, I place a few ice cubes in a plastic bag and put the bag in the freezer. If the ice has melted and refrozen by the time I get home, I'll know we've had a power outage and that any food left in the refrigerator may be unsafe to consume.

I teach a Tulane University seminar on independent European travel for first-timers. Until recently, I advocated Europe's great rail networks as the way to go. Now, with the plethora of budget airlines, I recommend a combination of the two. But it makes the planning stage—which I find almost as much fun as actually taking the trip—more involved. Thank goodness for whichbudget.com, a Web site that lists, by city, which budget airlines serve which cities. Then, to find links to all of Europe's state railway Web sites, visit railfaneurope.net. Each site generally features a travel planner and, almost invariably, an English-language option.

If your tablecloth is wet at dinner, you should prepare for rough seas. Restaurant staffers have been known to slightly dampen the tablecloth to keep plates and glasses from sliding.

Pack a power strip and extension cord for your next cruise. Many cruise-ship cabins have only one out- let, but you'll definitely need more if you want to power up your laptop, iPod, cell phone, electric razor, hairdryer, or any other gadgets you bring on board.

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

My husband cut an old contact lens case in two and uses the halves to carry his medication when we're traveling. He prefers them to regular pillboxes because lens cases are watertight and compact enough to carry inside a shirt pocket.

Whenever my husband and I get new pairs of eyeglasses, we relegate the old ones to our luggage, along with an inexpensive repair kit from the drugstore. If something happens while we're away from home, we can hopefully fix the glasses ourselves. If they're beyond saving, we have the backup pairs to get us through the rest of the trip.

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.

Paper place mats can be useful anywhere there's an outdoor shower. By stepping onto a place mat after a bush shower in Botswana, I managed to keep my feet clean and avoided getting dirt in my clothes.

My husband and I always travel around Europe by train. When we arrive in any city, we first stop at a ticket window and get all the information we'll need for the next leg of our journey. This gives us plenty of time to find an English-speaking ticket agent who'll print out departure times and platform numbers for us. Before leaving the station, we can note the location of the platform we'll be looking for that morning. One wrong move when you're rushing for a train and you could end up in the wrong city!

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.

The best carry-on bag that I've found is a gardener's tote. It has lots of pockets on the outside and room inside for a medium-size purse, yet it's small enough to sit comfortably at my feet on a bus or plane.

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.

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.

Before exchanging foreign currency at the airport, find out if there's a departure tax. At the Bangkok airport, we were very upset- as were travelers around us- to find we had to pay a fee before continuing to our gate. Unfortunately, by that point everyone had cashed in their baht, so the options were a conveniently located ATM, a credit card, or an exchange booth with notably poor rates. When we described this incident to friends, they told us of a similar experience when trying to leave the Dominican Republic.

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.

Whenever I go somewhere, I bring a supply of postcards from my hometown. I write my name, address, and e-mail on the back, and offer a card to new friends so we can keep in touch. I also pack small souvenirs (key rings, etc.) that carry my local sports teams' logos. They make meaningful but inexpensive thank-you gifts for the small kindnesses that ease one's way during a trip.

I don't go anywhere without individual packets of antibacterial wipes. I slip some in my carry-on, daypack, and shirt pocket. They're very convenient when you can't find any running water with which to wash your hands. And because they're antibacterial, they're also great for cleaning cuts, and the alcohol from the wipes helps stop the itching when you rub them on insect bites.
