10 Small Museums in Washington, D.C.

Batteries for cameras, laptops, cell phones, and other devices can be charged at night in your hotel room. But if you're doing a lot of driving, you might want to buy an inverter to charge them while on the road. Inverters (which plug into the car's cigarette lighter) are small, inexpensive, and can be purchased at auto-supply, variety, or electronics stores.

If you start to feel a painful blister coming on, put some lip balm or Vaseline on the hot spot--it'll help stop the rubbing.

Consider asking your driver or tour guide to haggle on your behalf at bazaars and souks. (But don't let them lead you to places where they might have a connection to the shopkeeper.) The money you tip them will usually be less than the markup on prices for tourists.

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.

Attach a few carabiners--the kind of clips rock climbers use--to the top of your wheeled suitcase. Purses, cameras, and shopping bags can be clipped to your suitcase, giving your hands and shoulders a rest while you're walking around the airport.

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.

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!

Don't save the best for the last day. If you wait until the end of your trip for "must-do" activities, you won't be able to reschedule if something unforeseen happens. I planned a snorkeling excursion for my final day in San Diego, but the waters were too rough, and the trip had to be canceled.

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.

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.

I was heading to the hotel ice machine when I noticed that our ice bucket was looking very tired and missing its disposable plastic liner. My solution: the shower cap that we never use anyway. In fact, it actually worked better than the liner bag because the elastic band held it in place around the top of the bucket.

I enjoy off-peak travel best--rates are cheaper, lines are shorter--but the weather can be iffy. To combat Mother Nature's unpredictability, I always pack a roll or two of black-and-white film. While dreary-day color photos bring only consoling remarks from friends, black-and-white film tends to lend a mystique to gray landscapes and creates some very dramatic Ansel Adams--esque shots.

When we come home at night, my wife and I each take a dollar from our wallets and put them in a special spot. We deposit what we've collected into a travel account at our bank every few months, so at the end of a year, we have $730 toward our next vacation—not counting interest.

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.

To save space, pack items for travel that you can use in at least two ways. In a pinch, shampoo can double for detergent when washing your clothes (carry the bottle in a Ziploc bag in your suitcase); sandals or flip-flops also function as slippers; and a swimsuit cover-up can serve as a bathrobe.

Before booking your next ski trip or reserving a table for dinner, find out what your credit card company has to offer. American Express sometimes has discounts on lift tickets; MasterCard has offered buy-one-get-one-free at local restaurants; and Discover Card has access to deals to Universal Studios. Check out americanexpress.com/offerzone, mastercard.com (be sure to click on Promotions), and discovercard.com.

If you've accumulated more souvenirs on your trip than you can carry, drive your rental car up to curbside check-in, then return the vehicle and come back on the shuttle bus with only your carry-on. This only works if there's no check-in line, but can save dragging your luggage onto the shuttle bus, across parking lots, etc.

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.

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.

When I'm packing to leave a hotel room, I turn the bedding down to the foot of the bed so that the white sheets are facing up. This way, items placed on the bed are clearly visible. I once left a camera behind because I couldn't see it against a very dark bedspread.

We always e-mail our itinerary--including flights, hotels, and confirmation numbers--to ourselves and to family members. If our luggage is lost or our wallets are stolen, all of this essential information is just an Internet café and a few quick clicks away.

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.

A simple but effective anti-pickpocketing measure is to fasten a safety pin across the opening of the pants pocket on the inside. Leave enough room to pull your wallet out with some effort, but not enough for a quick hand to lift it in a second or two.

If you can't sleep due to the heat in your non-air-conditioned hotel room, take a cold bottle of water and place it on your pillow, in the crook of your neck. It will cool your whole body down.

I don't go anywhere without individual packets of antibacterial wipes. I slip some in my carry-on, daypack, and shirt pocket. They're very convenient when you can't find any running water with which to wash your hands. And because they're antibacterial, they're also great for cleaning cuts, and the alcohol from the wipes helps stop the itching when you rub them on insect bites.

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.

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.

I'm a gadget freak, and I don't like to travel without things like my digital camera and iPod. On one trip, though, I put my camera down in a crowded restaurant and then forgot to put it back in my bag. By the time I remembered it, the camera was long gone. Now, I attach those kinds of items to my daypack with a lanyard. They're still easy to pull out and use, and they never get left behind.

Once we know where we're going, my girlfriends and I divide up the list of things we'd like to do on our trip and put someone in charge of each item on the list. Then that person does the legwork by finding directions and prices, making reservations (if necessary), and researching nearby places to stop for a snack or a meal. Our method means that no one person is doing all the planning.

When looking for the lowest airfare, I've found that in some cases the best rates pop up when searching for one traveler instead of two. Recently, I wanted to buy one-way tickets from New York to Orlando for two people and came up with $87 per person. But when I selected one traveler, the fare dropped to $72.
