I started saving the heavy-duty plastic wrappers that sheets and curtains come in. Most have zippers or snaps, great to hold everything from toiletries to shoes to wet swimsuits. And I bet airport security must love them because they're see-through.

Finding healthy breakfast alternatives at an airport can prove difficult. I always travel with an insulated travel mug. Before leaving home I fill it with a high-protein cereal and then request low-fat milk on the flight.

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.

Lightweight, washable, and multifunctional, a cotton sarong is an easy and practical addition to every traveler's don't-leave-home-without-it bag! I've used mine as a swimsuit cover-up, as a picnic blanket on the grounds of a château in the Loire Valley, as a temporary skirt (over my shorts) in a Bangkok temple, and as an extra pillow while hiking the South Rim of the Grand Canyon. It's also handy as an airplane blanket, emergency towel, or tablecloth.

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.

By the time I got home from my first trip to Europe in 1963, I'd collected menus from several restaurants I liked. I threw them into a box. In 1988, I returned to Europe and went to the Middle East. Once again, I picked up a few menus. This time I had them all framed and they now hang in my kitchen. Since then, I've added to the collection. It's fun looking at the prices and remembering the good times—plus they make great conversation pieces when I have a party.

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.

If your flight is canceled, don't just wait patiently in line to be booked on another flight; call the airline's 800 number. They'll answer your call faster, and you won't be waiting with other stranded passengers from that flight. (Or cover all bases by calling while in line.)

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.

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.

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.

Water-bottle holsters are good for more than holding water. I own several Water Bottle Totes by Outdoor Research (orgear.com). With their Velcro-like straps, I can fasten them anywher--to my belt, camera strap, fanny pack, purse, or airplane seat. I've used them at various times to carry my camera, binoculars, snacks, umbrella, battery-powered fan, flashlight, sunglasses, a windbreaker, and a rain poncho.

If you're divorced and plan to travel out of the country with your children, check the legal requirements in advance. When I tried to take my kids to Cancun, I learned too late that Mexico requires a notarized letter of consent signed by both parents for minors traveling alone or with one parent or guardian. If the parents are divorced, a copy of the parental custody agreement is allowed instead. The airlines enforce this rule before you get on the plane.

My husband and I are retired, and we take two trips abroad each year. When unpacking, I put items we use repeatedly on each trip (flashlight, alarm clock, travel-size toiletries, etc.) into a box and keep it stored near the suitcases. No more searching or trying to remember if I've got everything for the next journey—it's all in one place.

Tired of catching colds while traveling? Take along a travel-size package of Clorox wipes. Disinfect the tray table and armrests on the airplane, and the telephone and TV remote in your hotel room.

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.

Here's an important tip for cruising in winter: Fly into the port a day or two before your ship is scheduled to depart. We booked a Costa Rican cruise but were stuck in New York, where all flights out of JFK airport were canceled. Itineraries that include stops in places with airports can allow people to catch up. Ours didn't.

If the porters haven't delivered your luggage to your door by the first night of the cruise, check what our experts call the "naughty room." Security will store any bags containing contraband (like candles, alcohol, or coffeemakers) in this centralized location until you come claim it. You'll be able to pick up your bag on the first night, but banned items will not be returned until the end of the trip.

Public libraries in the ports of Alaska are a tremendous money-saver. Who wants to pay $5 a minute for Internet use from a cruise ship? During a port stop on a recent Alaska cruise, we found a city library that offered free Internet use for 15 to 30 minutes. Our only cost was a short wait in line.

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.

Before using frequent-flier miles, investigate how much the flight actually costs. For example, it takes at least 25,000 miles per person to travel from Boston to Alaska. The same flight cost us $288. After paying for our tickets, we received enough additional miles to travel for free to Sweden instead of Alaska!

Priceline was a total pig in a poke for me, so I never used the web site, until I found out about biddingfortravel.com. This helpful Web site gives potential bidders an idea of prices that are being accepted (and declined) on priceline.com for particular dates and properties (or airfares or car rentals). I got the Hyatt Regency Miami for $35 per night because of this!

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!

Baby wipes aren't just for babies. Slip a travel-size pack into your carry-on bag and use the wipes to kill germs on public toilet seats and in phone booths. In a pinch, they can also remove stubborn stains from clothing.

Before traveling to any city, do a search on the Internet of the city name and the word "coupon" ("New Orleans coupon"). You will find many sites offering two-for-one, percentage-off, and dollar-off discounts. On a recent trip to St.Louis, we saved $100 at restaurants and attractions.

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.

If you're packing a lunch to eat later in the day, freeze a 16-ounce water bottle and pack it, along with yogurt, cottage cheese, a ham sandwich, or whatever in a light- weight, insulated bag. Your snacks will remain cold, and you can drink the water.

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!

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.

The middle seat isn't always awful. On a recent trip overseas, I called too late to confirm an aisle or window seat. After explaining the plane's AB-CDEFG-HI configuration, the customer service agent urged me to take the very middle seat, E, because D and F have less foot room. (In some rows, there are metal boxes underneath the seats in front of you that house wiring for onboard electronics.) I went along with her advice somewhat skeptically, but I ended up with plenty of room. The people on either side of me weren't so lucky.
