Online Resource Guide: Gadgets, Gear and Travel Tech

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.

When you're shopping for alcohol on any Caribbean island, ask if there's a Kmart nearby. Often the dis- counter is a short distance from the docks where the cruise ships tie up and has an extensive selection at prices lower than the liquor stores on the main drag. While you're there, pick up that extra roll of film or the sunscreen you forgot.

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

When I called to book a hotel room in Budapest, I was offered a rate of $75 per night. After I told the concierge that I was looking for a room in the $35 range, he agreed to the lower price without much fuss. It sometimes pays to barter.

During a visit to Mexico City, I was sitting in a plaza near a fountain, watching the locals stroll around in their Sunday best. Nearby, an older gentleman was playing a concertina; his music perfectly framed the scene. I took lots of pictures, but I didn't have a way to capture that music. Now I pack a small tape recorder along with my camera.

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.

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!

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!

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.

If you're traveling solo and your room has a double bed, sleep on the side farthest from the phone. It's slept on less frequently and is therefore more comfortable.

There's nothing worse than trying to fall asleep under a mosquito net and then realizing that the bugs are finding a way inside. So next time you're heading someplace tropical--where you know you'll be sleeping under mosquito netting--remember to toss a roll of Scotch tape into your suitcase. It's perfect for quick repairs.

Before leaving for a vacation, I print out all our reservations and directions, and I create a contact sheet for emergencies. Then I gather all the papers together, punch some holes, and place them in a folder that has a middle section for three–holed papers. The side pockets hold brochures, business cards, ticket stubs, receipts, and maps that we collect along the way and want to bring home for our scrapbook.

Before traveling overseas, look at your health insurance card. If it only shows an 800 or 888 number for precertification of hospital admissions, call that number and obtain the local number with an area code. Many 800 numbers can't be dialed from foreign countries. I learned this the hard way during an emergency hospital admission in Switzerland. The delay in reaching my carrier could have been avoided.

Driving around Italy last summer, my husband and I found that even the most detailed maps left us scratching our heads in confusion. Desperate and lost, we decided to follow a tour bus. Guess what? It got us exactly where we wanted to go.

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!

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 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.

Give your children a coach's whistle in case they get lost; put it on a ribbon so they can wear it around their neck. The piercing sound may be annoying, but you'll definitely find them quicker!

After I was unable to locate any awards seats online for a wide selection of days and routes, I called the airline. An agent told me that the airline's Web site isn't allowed to book awards seats for its partner airlines, but agents can. Within minutes, I had enough options that I found it difficult to make a decision.

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.

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.

Put a few plastic trash bags in the outer pockets of your suitcases and carry-ons. If you arrive at your destination and it's raining, you can cover your luggage with the bags while you make your way to your hotel. Just cut a slit for handles or straps.

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.

If you get lost on a ship, remember that most share a common layout. The lido-deck buffet restaurant, for example, will almost always be in the back to accommodate comfortable outdoor seating in the least windy part of the ship, while the lounge/theater will be in the front because wind is not a factor (there are no windows).

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.

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.

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.

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.

I always bring a small flashlight to hotels in case there's a blackout. The building may not be equipped with emergency lighting, and, if necessary, my flashlight will help me quickly locate the nearest exit.

We rented a car last summer to tour northern Italy. Initially, we contacted Europcar (europcar.com) and got a quote of more than $500. We then clicked on a rental-car link from Best Fares (bestfares.com) and received an offer that knocked off about $50. When we mentioned to Europcar that we'd seen lower offers on the Web, they told us that if we sent them the URL and they could verify the offer, they'd match it. We eventually found a car that was an additional $100 cheaper from a British company. Europcar-which offered better service for our itinerary-accepted that lower price, saving us $150.
