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.

Traveling to non-English-speaking countries can be daunting for people with food allergies. Find someone fluent in the local language to write out what you are allergic to, the seriousness of the allergy (we had a friend include the phrase "this could kill me"), and what to do if you fall ill.

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.

I travel with two cameras: a digital SLR for the majority of my shots, and a small disposable camera for when I ask strangers to take pictures of me. As much as I tend to trust other people, I'm not ready to hand over my $1,000 camera to someone I don't know at all.

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.

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.

For our road trip through the English countryside, I printed out a detailed map for every location we wanted to visit from multimap.com. I labeled each map with the day we planned on using it and wrote down the interesting sites and places to eat along the way. I kept them all in a folder and added brochures from the places we saw. It was a great souvenir upon returning home.

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.

I used to lug around a clothes steamer and adapter to stay wrinkle-free while on the road, but I've since opted for something more low-tech. I now travel with a Platypus collapsible bottle and a spray bottle head. After checking into my hotel, I immediately hang my clothes and give them a spritz with water from the spray bottle. After several hours, the wrinkles fall out, and the clothing is dry and ready to wear.

Make a master list of jobs to do around the house before you leave (hold the mail, water the plants, take out the garbage). Keep the list on your computer, print it out, then check off each job as it gets done. You'll be able to go without worrying that you forgot to stop the newspaper.

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.

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.

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.

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.

We all know to avoid drinking tap water in certain countries, but remember to forgo ice cubes, too. I've started bringing along two ice trays, which I fill with bottled water and freeze in my hotel room's mini-fridge.

Avoid spills in your Dopp kit. Cut up plastic grocery bags into little squares and place them under the tops of toiletries to prevent leaks. Discard the squares upon arrival, but bring extras for the trip back.

Pack a travel-size shampoo container refilled with detergent and a one-gallon Ziploc bag for when you need to wash hosiery, bras, and other delicate undergarments. Put a few drops of detergent into the bag and fill it part way with water. Place the garment in the bag, close it up, and shake it around for a few minutes. Instant washing machine! For larger pieces of clothing, I've used the plastic laundry bags supplied at most hotels. Just hold on to the open end tightly.

Turn off your fridge's icemaker before you leave home. And remember to empty the ice cube bin. The power was out for several days while I was away recently. When I got back, the melted ice had refrozen throughout the freezer compartment. It took forever to clean up.

When on vacation, I split my cash into envelopes, one per day, so I can keep track of how much I'm spending. If I need to dig into the next day's cash, I'll know that I've overdone it, and if I want to stay on budget, I'll have to cut back the next day. Any money left at the end of the day goes into a separate envelope. I've actually come home with money this way!

Frequent fliers should consider noise-cancellation headphones. They have a built-in device that "hears" low-frequency sound just before you do and generates a sound wave that cancels it out. Several manufacturers make them, ranging in price from $40 to $300 or so.

Booking condos last minute can yield incredible bargains, and there's a way to maximize savings while minimizing the risk that you won't find a room at all. ("Last minute" generally means a month or less before your stay; seven-day deals usually start on a Saturday.) Buy your plane ticket and book a refundable hotel room you can use in case you can't find that bargain condo. Then, a month or so before your trip, start looking at last-minute sites—lastminutetravel.com, site59.com, etc. If you find a deal, simply get a refund on the hotel room and pay the cancellation fee, if there happens to be one. Using this technique, I found a great beachfront, one-bedroom condo on Maui—and I saved about $300.

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!

Anyone tired of the same boring postcards that are found at every roadside tourist trap should try shopping for vintage postcards at an antiques shop. They're a great addition to any photo album, as they often show what the local attractions looked like prior to development.

I bought several items while in London and noticed when I returned home that my credit card number was printed in full on each sales slip. (In the United States, usually only the last four digits of the number are visible.) Travelers should be careful when using their credit cards overseas--don't leave the sales slips lying around.

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.

Don't assume you can save a spot at the pool with your towel. Cruise lines give you one pool towel at the start of the cruise. If you don't have it (or a cleaned trade-in) at the end, you'll get charged. If you let it out of your sight, you run the risk of losing it or having it stolen by a fellow cruiser.

We decided to take our bikes on our last Caribbean cruise. It was a little crowded in the cabin, so the steward let us store them down the hall with the wheelchairs. We were last off the ship when we docked in Bermuda, but after five minutes we'd left our fellow passengers in the dust. And in less than fifteen minutes, we were far away from the busy port, enjoying a beautiful, deserted snorkeling beach.

Bring your own linens. They're useful in a million different ways. Obviously a soft cotton pillowcase makes those scratchy airplane pillows bearable, but it can also be used to gather loose items when deplaning. A nice sheet will cover up an ugly bedspread or sofa, and makes a great tablecloth or picnic blanket.

When my husband and I would stay in a hotel with our two-year-old, a full night's sleep was out of the question. The minute our son opened his eyes (at 2,3,or 4 a.m.), he woke us, thinking it was time to play. We now pack a pop-up tent and set it up in a corner of the hotel room with books, a blanket, and a few small stuffed animals. The tent folds down to a 14-inch circle and weighs about a pound. It works great! My son has his own "room" to sleep in when we vacation, and we all get to sleep through the night!

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.
