Unfasten Your Seat Belts!

Remember to check the hours of operation for your hotel's airport shuttle. In Rome,we were surprised to learn that our hotel--which touted its shuttle--only offered the service a few hours a day.

When carrying around my small umbrella, I put it in a Ziploc bag. After using it, I can store the umbrella, back inside the Ziploc, in my shoulder bag without getting everything else soaked.

If you're a woman traveling alone, or your accommodations don't inspire confidence, simply wedge a small rubber doorstop at the base of the door when you're inside the room. It'll be virtually impossible to open the door from the outside.

A beach ball can replace many expensive in-flight gadgets. Depending on how much you inflate it, the ball can function as a very comfortable footrest, a back support, or a lap pillow to support your book.

A shoe organizer hung over the bathroom door is my solution for hotel-room clutter. The compartments are perfect for stashing everything from room keys and travel documents to toiletries and, of course, shoes. The extra storage space came in especially handy on a recent cruise, when we needed all the room we could get in our tiny cabin.

I always have problems locating my rental car in a large parking lot. Now I bring along a brightly colored bandanna and tie it to the antenna.

By starting a blog for each trip--at blogger.com, among others--you can keep your friends and family up-to-date on your adventures. All you need is an Internet café to add entries and photos while you're on the road.

For overnight flights, pack a few Oral B Brush-Ups in your carry-on. Before the plane lands, you can "brush" your teeth, leaving you refreshed and ready for the day!

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.

Ziploc now makes extra-large bags with handles. They're nearly two feet by two feet, and although Ziploc advertises them as being good for storage, they're also useful for traveling. Bring one on long shopping excursions and then use it as an extra carry-on for souvenirs on the way home.

It can be difficult for parents to find a place to bathe their infant while on vacation. Showers obviously won't work, and the miniscule sinks generally found in hotel bathrooms aren't appropriate either. On our last cruise, we eliminated the whole problem by packing a small, inexpensive inflatable bathtub. (Ours cost only $7.99.) When we arrived, we blew it up and placed it in the bottom of the shower for an instant, safe baby bath.

When I'm on a cruise with my wife's family and we're in a foreign city for the day, I get off the boat as soon as we dock and hail a taxi. I ask the driver to call his dispatcher and find me a van with an English-speaking driver. Then I negotiate an hourly rate and a pickup time at the dock. The family tours together for a few hours, and then each couple either gets dropped off where they want to spend extra time or returns to the boat (this is great for my elderly in-laws). We get a tailor-made city tour for a much cheaper rate than if we had booked through the cruise line.

If you make a hotel reservation online and then cancel online, print out and save the cancellation confirmation for at least two billing cycles past your trip. After our vacation, I found a "no-show" charge on my credit card for a room that I'd canceled well in advance. Without the confirmation, I had no way to contest the bill.

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.

I've discovered a wonderful way to enjoy massages at a fraction of the usual cost. Some massage-training schools provide superb service in a spa-type environment. Do a Google search to see if there are training programs near your next vacation destination.

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.

I always try to work out before heading to the airport. It usually gets me tuckered out enough that I can relax and sleep on the plane. If I don't have time for pre-travel exercise, I take a brisk walk through the terminal before boarding or find a quiet spot in an empty gate for a little yoga.

If you're traveling with someone, discuss a central meeting place in case you get separated. My husband and I were in Paris waiting to board the Metro. He was able to board the train, but I was left behind on the platform. Having a plan saved both time and needless anxiety.

Always carry peanut butter. A plastic jar is easy to pack, doesn't need refrigeration, is a great source of protein, and makes a quick, cheap meal when coupled with local bread. (But don't forget to pack a plastic knife for spreading it.)

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.

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.

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

Some cruise lines offer discounts on a future sailing if you book it while on a current cruise. Back home, you can transfer the booking to your travel agent and work with them to try to lower the price even further. You'll be able to cancel your booking at no cost if you follow the cruise line's cancellation schedule. This is a great way to get some of your onboard expenses paid for in advance.

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.

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.

During the hot months of summer, I plan to travel with a very small spray bottle. I'll fill it with water and use it as a mister to keep cool. I got this idea when we stayed at the Noga Hilton in Cannes. On the dresser was a pink aerosol can full of Evian water. I took it with us sightseeing and, wow, it was so refreshing to spritz water on our faces.

Sending a flat-rate Priority Mail box costs $8.10, no matter how much it weighs or which state it's going to. After accumulating too much stuff to fit in my suitcase during a trip to Atlanta, I filled a box with laundry, souvenirs, and gifts for my grandchildren, and mailed it to my home address.

I prefer laminated city maps because I can circle all the things I want to see in a given day with a dark erasable marker. Once I have everything marked, I plan my route and start walking. The next day, I erase the previous day's marks and begin all over again.

Accidentally reformat your camera's memory card? As long as you don't overwrite the disk by shooting more photos, those original pictures are still there. Buy another card to use in the meantime, and then, when you get home, either purchase a file-recovery software program (about $35) or take the card to a camera shop and see if someone there can help.

If your travels take you to U.S. cities large enough to have museums, zoos, and/or botanical gardens, consider buying a membership in your home city's counterpart. Many have reciprocal privileges with institutions elsewhere. A membership at Chicago's Lincoln Park Zoo, for example, lets you see the National Zoo in Washington, D.C., and zoos in Los Angeles, Des Moines, and Jackson, Mississippi, at no charge.
