Have a Green Stay

Sign up for guest programs at every hotel chain that offers one, even if you haven't stayed at that hotel before or think you may not travel enough to reap benefits from multiple stays. Some programs send coupons for discounted rooms or complimentary room upgrades just for being a member. After signing up for the Omni Hotels Select Guest program, I received a coupon that I was able to redeem for a room in Chicago for $80 per night.

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.

Ever since my children were small, I've carried recent, wallet-size pictures of them when we all go on vacation, in case we get separated. Now that they are teenagers and traveling with friends' families, too, I send pictures for the other family to bring along with them. I also write my telephone numbers on the back of the pictures so they know where to reach me in an emergency.

Dry-cleaning bags stop clothes from wrinkling. Slide each garment into its own bag (leave the hanger at home) and place them flat on your bed, one on top of another. Then carefully fold the entire stack to fit it in your suitcase. Once you get to your hotel, hang everything up as soon as you can. You'll never unpack a suitcase of wrinkled clothes again.

Everyone knows that duct tape is great for helping out in travel emergencies, but no one wants to lug around a bulky roll of the stuff. By wrapping a few feet onto a pencil or ballpoint pen, you'll get a miniature roll that does not take up much in the way of additional space.

If I plan to travel to several countries that use different currencies, I pack a few cloth change purses: U.S. dollars go into one, British pounds in another, euros in a third, etc. When I'm sightseeing, I carry only the money I need; the purses that I'm not using are locked away in the hotel safe. I avoid fumbling around in shops and mixing up coins that look alike. Plus,I always know exactly how much cash I have.

If you plan to travel to a less-developed country, pack an extra suitcase with hand-me-downs of all sizes. Housekeepers and other resort workers make so little money that the clothes are greatly appreciated. On your way home, you can use that empty suitcase for souvenirs.

Even if you're staying at a standard resort hotel, take advantage of the day passes sold by many all-inclusive resorts (i.e., the right to use their facilities--such as swimming pools and beach chairs--and enjoy their meals for a day). The passes are primarily designed for cruise passengers on day trips but can be obtained by anyone for very little money. For persons staying in a less-expensive, no-frills hotel, it can give you the experience of a larger, more extensive resort for a day or two.

Check fares periodically after booking your airfare. The airline may have a sale, and buying new tickets could save you money, even after you pay the change penalty. My wife and I used Travelocity's Fare Finder to pocket $187 each on a recent trip from Seattle to New York City, simply by re-ticketing.

If you're traveling solo and want some company for dinner, try the sushi bar at a Japanese restaurant. It's a great place to meet locals. Plus, you'll receive extra attention and special recommendations from the chef.

When my husband and I travel, we take at least three different credit cards. I carry one he doesn't have, he carries one I don't have, and we both bring our primary card. If one of us has our wallet stolen, we can cancel two cards and still have one to use. We each have different ATM cards, too--useful if a machine doesn't honor one of the cards, or if we need more cash than our daily limit allows.

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!

Internet phone services like Vonage can be programmed to send transcribed voice mails to your email in-box. That way, you can check your home answering machine quickly at an Internet cafe without paying insane roaming fees on your cell. The transcriptions won't always be perfect, but you'll get the gist.

My husband and I befriended some locals in Provence by joining them in a game of petanque. It was such a memorable experience that now we brush up on local games each time we plan to travel abroad. We've played dominoes in Spain and bocce in Italy.

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 the zipper on your luggage or your clothing is giving you any trouble, rubbing some lip balm or candle wax onto the teeth should loosen it.

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.

My daughter and I bought disposable digital camcorders at a CVS pharmacy before going to Europe. It was a nice way to document our trip--each camera stored about 20 minutes of video. Once home, we dropped the cameras off at the pharmacy. The next day, our DVD was ready. We were very pleased with the quality and the cost: $30 for the camera and $13 for each DVD.

My husband and I create personal cards (like business cards) before we leave home. We put our name, address, phone, and email address on them, as well as a picture of us. How many people have gotten home from a trip, looked at a slip of paper with a name and address, and wondered, Who is this? The picture helps link a name to a face.

If you're stranded overnight at an airport and receive a "distress rate" voucher, call the hotel of your choice before blindly following the airline's suggestion. You may find that for that discounted rate (or a few bucks more) you can stay in a hotel with a lot more amenities than the one the airline would put you in. After a long, mishap-filled trip, anyone can appreciate a really good mattress, a top-notch restaurant, and an indoor swimming pool.

Pick just two colors to mix and match throughout your trip. You'll cut down on luggage, not least because you won't have to bring a bunch of shoes to match a wide assortment of colors.

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.

I travel with a mailing tube in my suitcase because I often buy paintings, drawings, and maps. My souvenirs always arrive home safe and sound. I just leave the mailing tube in my suitcase until the next trip.

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.

Spring skiing often means a wild temperature shift from morning to afternoon. If you want the option of removing outer layers or switching to a lighter ski jacket midday, attach the lift ticket to your clothing with a split-ring key ring. You'll be able to move your ticket as the weather warms up.

Don't settle for the first answer to your travel question. If you need flight information, it's a good idea to phone the airline more than once and ask the same question. Recently, I wanted to see if I could fly standby on an earlier flight the same day. The first time I called, I was told that the earlier flight was booked. The second time, however, an agent said there were in fact seats available, and I could certainly fly standby. In the end, not only was I able to get on the flight, but I was upgraded to first class.

Using your frequent-flier miles, you might be able to visit two cities on one ticket. For example, my wife and I always trade in our Delta miles when we visit our daughters in Dallas and San Francisco. Because we have to fly through Dallas to get to San Francisco on Delta, we can stop over in Dallas for as long as we want before continuing on to San Francisco—and we use only one frequent-flier ticket each.

Before I embark on a trip, I cover the dirt of my potted plants with plastic bags after watering them well. (Cut a few slits in the bags and keep plants out of direct sunlight.) The soil will stay damp for about three weeks.

Preserve even the small number of frequent-flier miles you may obtain by making occasional use of a particular carrier; the miles can be worth money. Even if you don't regularly fly on Delta, Northwest, Continental, or several other airlines, sign up for their frequent-flier programs when you book a long or overseas flight. Points.com allows you to redeem miles for magazine subscriptions, music downloads, and other products. You can also use miles to get small discounts on purchases at retailers such as Amazon.com.
