Top U.S. Water Parks

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.

You can enjoy free airport-area parking by staying the night before departure at an airport hotel or motel that offers park-and-fly rates. The cost of that overnight (which usually entitles you to two weeks of parking) is much less than what you'd otherwise pay at an airport parking lot.

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.

Before exchanging foreign currency at the airport, find out if there's a departure tax. At the Bangkok airport, we were very upset- as were travelers around us- to find we had to pay a fee before continuing to our gate. Unfortunately, by that point everyone had cashed in their baht, so the options were a conveniently located ATM, a credit card, or an exchange booth with notably poor rates. When we described this incident to friends, they told us of a similar experience when trying to leave the Dominican Republic.

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.

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.

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.

Every summer, we drive out West from Pennsylvania with our two kids. To avoid that infamous road trip question ("Are we there yet?"), I give each child a map with our route highlighted on it. Along the way, they can match up the town names with road signs we pass, and that way, they always know exactly where we are and how much farther we have to go until we'll get there.

Many tourist information offices provide discounted same-day booking services for local lodgings. My husband and I discovered this when we accidentally left a midweek gap in our travel plans between my husband's conference hotel and our B&B in Charleston. Instead of adding another night at either location, we stayed at one of the more elegant inns (normally over $200) for $70, courtesy of the Charleston Convention and Visitors Bureau.

Instead of bringing one of those bungee cables to hang-dry my delicates and socks, I pack a couple of mini plastic hangers--the ones that bras and panties come on when you buy them. They take up very little room in my luggage and can be thrown away at the end of the trip.

I've found that by wedging a bath mat under my hotel-room door, I can reduce any light or noise coming from the hallway—ensuring that I'll sleep better.

We've noticed that when booking a flight for our family under one reservation, some airlines will only credit the 1,500 bonus miles (500 for booking online, 500 each way for printing boarding passes) to the person whose name the reservation is under. This is regardless of whether the other family members have mileage accounts. To avoid this, make a separate reservation for each of your family members and then pick seats together.

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.

We were told by an airport security official to tape a business card onto the cover of our laptop. Turns out he has an average of six laptop computers left behind each day! There are so many more procedures now--removing shoes, removing coats--that people forget when they send their laptop through in a separate bin. The official added that it's very difficult to return them because most laptops have passwords that keep the owners' personal information hidden.

I always pack a Petzl Tikka Plus headlamp. It's small, weighs next to nothing, and is perfect for reading in bed at night without disturbing my husband. They're sold online and at outdoor-gear stores for about $33.

When I travel for business, I usually tack on a few extra days to do something active like hike in a nearby national park. I find that by taking two small suitcases instead of a single large one, I stay better organized and less burdened. I keep my business clothes, papers, and laptop in one bag and hiking clothes and gear in another. I leave the suitcase I'm not using at the time in the rental car and easily carry the lightweight case with the equipment and clothes I need into my hotel.

If you're on a road trip with young children and you're looking for a place to let them blow off some steam, check out the playgrounds at local elementary schools. They almost always have equipment that your children will love to explore. It will also give everyone in the family a welcome chance to stretch their legs.

For long overnight flights, pack a dry washcloth in a Ziploc bag in your carry-on. Before landing, ask the flight attendant for a cup of hot (not boiling) water. Carefully pour the water into the Ziploc bag and then wipe your face and hands with the steaming cloth. It's like a portable sauna!

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.

Public libraries in the ports of Alaska are a tremendous money-saver. Who wants to pay $5 a minute for Internet use from a cruise ship? During a port stop on a recent Alaska cruise, we found a city library that offered free Internet use for 15 to 30 minutes. Our only cost was a short wait in line.

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.

Check out grocery stores in Europe for bargains on wine. On our last trip to Italy, I found a 1993 Banfi Brunello in a small market for $16. If I could find it at all in my local wine shop, that same bottle would cost more than $100. I only wish I had listened to my husband and bought all three of the bottles the store had.

No longer do the many key chains I get as advertising languish in bureau drawers. I attach one or two at the ends of my luggage zippers. They make it easier to work the zippers and help me identify my luggage on airport carousels.

Though they're often the best deals around, don't assume that packaged vacations always offer the biggest bang for your buck. My wife and I were ready to book an air/hotel package to Maui when we noticed a sale on Aloha Airlines ($280 round trip from Oakland). I added up the total cost of the trip if purchased separately and saved $400 over comparable packages from various tour operators. We used the extra money to stay in a nicer hotel and to rent a convertible!

Put your perfume and cologne bottles inside pairs of rolled-up socks to keep them cushioned during your journey.

We like to buy shipboard souvenirs, so we try to choose a ship that's completing its run of an area--that's when merchandise is generally put on sale. Last year, for example, on a sailing in South America, all of the T-shirts, glassware, and rain jackets were 75 percent off.

If you're headed to a country that requires a visa, ask the consulate of that country, in the United States, whether visas are also issued at the airport there on arrival. In many cases (like Turkey and Egypt), they are. Obtaining the visa on arrival is a much simpler procedure and a real money-saver: You do not have to have photographs taken (they figure your passport already has a photo), you do not pay a hefty fee to the U.S.-situated consulate of the country, you avoid the expense and risk of mailing your passport to that consulate in advance of departure, and you avoid the expense of using a visa-acquiring company in the United States. But be sure the consulate is correct that the visa can easily be obtained on arrival.

It's easy to lose track of time in a windowless interior cabin. Before going to sleep, tune into the ship's bridge-camera channel for real-time videos of the front (or bow) of the boat. The screen will act like a virtual porthole, and you'll rise and shine with the sunrise.

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.

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.
