Sardinia: Italy's Island Surprise

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.

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!

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.

Make your cabin homier by packing a small collapsible vase and a bouquet of flowers.

Ask your flight attendants for dining, lodging, shopping, and sightseeing advice. Most crews have up to the minute information gleaned from layovers, which they're more than happy to share with passengers. You can count on flight attendants to seek out budget treasures. I know—I've been married to one for more than 21 years!

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.

Every year, I get address labels from numerous charitable organizations. I keep them with me when traveling because it's the quickest way to provide my address to new friends, enter prize drawings at shops, sign guest books, etc. It's not only efficient; it can also help spread the word about worthwhile charities.

Our bags have been stolen twice from inside locked rental cars. Now we travel with a bicycle cable and lock. If we absolutely have to leave our suitcases in the car, I hook them together by the handles and attach the whole thing to the frame of a seat or a secure item in the trunk. Even if thieves manage to get into our car, the cable will make it very difficult for them to make off with the luggage.

On a trip to Molokai, the plane we were on was small, and luggage was crammed in every which way. At baggage claim, we noticed that someone had packed a bottle of Pine-Sol, and it had broken and leaked everywhere. Now we line our suitcases with garbage bags to protect our clothes—just in case. (It's also smart in case your bag gets left on the tarmac in a downpour.)

For our road trip through the English countryside, I printed out a detailed map for every location we wanted to visit from multimap.com. I labeled each map with the day we planned on using it and wrote down the interesting sites and places to eat along the way. I kept them all in a folder and added brochures from the places we saw. It was a great souvenir upon returning home.

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.

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.

Save the flip-flops you're given at the nail salon after a pedicure. They make great shower shoes. They're lightweight and dry quickly, and you can throw them away at the end of your trip.

When seeking a cheap airfare, don't forget to consult the Web sites of the major charter tour operators--like Apple Vacations, TNT Vacations, Vacation Express, or SunTrips--which frequently sell air-only tickets in addition to air-and-hotel packages. Doing so helped me slash the cost of round-trip airfare to visit my mother in Las Vegas by well over 50 percent.

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.

Therm-a-Rest's Compressible Pillow is perfect for the plane. It comes in three sizes, packs smaller and expands bigger than any other pillow, and is machine washable. Whenever I pull mine out of my carry-on, I get jealous stares: People always ask where they can get one. REI sells the pillows for $18 to $25, depending on the size (rei.com).

I carry recipe cards with me to jot down interesting dishes I come across while on vacation. (I also like to use colorful postcards from the area I'm visiting and trim them to fit my recipe box.) Here's a wonderful dessert idea I brought home after spending a rainy afternoon with my husband in a London pub: Top a warm waffle with vanilla ice cream, maple syrup, and chopped pecans. It's heaven with a cup of hot tea.

If you plan to visit a theme park, always bring a few sandwich-size Ziploc bags. They'll protect your cell phone and wallet when you're riding on flumes and other water attractions.

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.

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.

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!

Put an address label on your one-time-use camera. At a Final Four game in Indianapolis, we exchanged identical Kodak Fun Savers with another traveler so that we could take souvenir photos of each other with our respective cameras. But afterward, we couldn't tell whose camera was whose. Luckily, I remembered how many exposures remained on mine, so we got ours back. Next time, I'll just label it.

Cruise lines offer packaged side trips at their ports of call. If you go online and look for these expeditions ahead of time, you can book directly with the tour companies and save money.

I always take a digital picture of the gas gauge to prove that I returned the rental car with a full tank. Some agencies try to charge for a minimal amount of gas when they "top off" the tank (which you're not supposed to do anyway). I've used these digital photographs to get refunds for gas charges that appeared on my credit-card bill after the fact.

We decided to take our bikes on our last Caribbean cruise. It was a little crowded in the cabin, so the steward let us store them down the hall with the wheelchairs. We were last off the ship when we docked in Bermuda, but after five minutes we'd left our fellow passengers in the dust. And in less than fifteen minutes, we were far away from the busy port, enjoying a beautiful, deserted snorkeling beach.

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.

The magnets you use on a refrigerator will also stick well to most hotel and motel room doors, turning them into makeshift bulletin boards. Post theater tickets, itineraries, reminder notes, and any other useful information, then grab what you need before you leave the room for the day.

Play Let's Make a Deal when you're shopping for vacations at travel shows or expos. Go armed with your own research and a credit card.(You're likely to get a better price if you know what the vacation is worth, and if you're willing to buy it on the spot.) I picked two Caribbean cruises and headed to the New York Times Travel Show. After haggling with the competing cruise lines, I was offered the first cruise for $50 less than the best price I'd found online, and they threw in free trip insurance. In the end, I chose the second—$30 off with a free upgrade to a balcony stateroom—and truly got a bargain.

If you plan to buy crafts in a country where bargaining is expected, use the time it takes for luggage to be unloaded to scope out the airport stores. Jot down items you like and their retail prices. If you find a similar item while touring the country, you have a top-end bargaining point. If you don't find the object at a better price, you can always pick it up at the airport while you're waiting for your flight home.

For fire-safety reasons, cabins don't have their own irons. Don't wait until the last minute to tackle your evening wardrobe. You can find shared irons down the hall in the laundry room, but lines often form before mealtimes. Opt for off-hours (like mornings).
