New York: Uptown

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.

Tell me I'm not alone: Almost every time I park my car at the airport, I have trouble finding it when I return. (I even reported my car stolen once after searching for hours, only to discover I was in the wrong lot!) I now use my cell phone to leave myself a message as to where I've parked my car.

A company called Orikaso makes brightly colored polypropylene sheets that can be folded--kind of like origami--to form a dish, bowl, or cup. The sheets are lightweight and reusable, and you simply flatten them when you're finished. We found ours at a sporting goods store, but you can also buy them online. Check orikaso.com for retailers.

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.

It helps to have a calculator if you plan to do a lot of shopping in foreign markets. When you find something you like, hand the seller the calculator and ask him to enter his best price. It's easy to convert the response into dollars so you know what you're spending. If necessary, the calculator can be used to haggle, especially if you don't speak the language.

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.

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.

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.

On the final day of a recent Caribbean vacation, I tried to arrange for a late checkout, but was told it wasn't possible. The hotel offered me the use of a day room; it would have been perfect, but it was being used by other guests, and there was a very long wait for the shower. I went back upstairs and saw that someone was just about to clean my room. I told the housekeeper that I understood she had to do her job, but I wondered if I could I take a quick shower first. She offered to clean next door while I took my shower. I tipped her $10 and then left for the airport.

Travel soap dishes--the colorful plastic ones that have hinged lids--stop small, fragile items from getting damaged or lost in your bags. I can easily label and use them again and again and again.

I like to bring a Frisbee when I travel. At the hotel, it's a convenient place to collect car keys, loose change, my ChapStick, and any other small objects I normally keep in my pockets. I always know where everything is, and things won't fall off the nightstand. It's also handy to have so you can play Frisbee at a nearby park or beach.

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.

Using restaurant.com, you can buy gift certificates good at eateries in your destination city, regularly snagging (in my experience) $25 certificates for as little as $5 to $8.The site is awesome, and it works as well for restaurant certificates in your own city and for obtaining gifts for friends.

On a Northwest flight from Wichita to Cleveland, a piece of my luggage was delivered more than a day after I arrived. In the meantime, I had to buy some replacement items. Save your receipts! I turned in the receipts when I checked in for the return flight, and the ticket agent issued me a $50 check.(Northwest allows up to $50 in interim expenses for the first 24 hours, and $25 for each day afterward, with a maximum reimbursement of $150.)

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.

To feed a family of four in a very expensive tropical location like Anguilla or Bermuda (or most other Caribbean locations, for that matter), check to see if your hotel has phone books and look up the local pizza place. Nine times out of ten the pizza purveyors will deliver for free. You'll end up spending no more than $20 on pizza, bread sticks, and soda.

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

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.

Play Let's Make a Deal when you're shopping for vacations at travel shows or expos. Go armed with your own research and a credit card.(You're likely to get a better price if you know what the vacation is worth, and if you're willing to buy it on the spot.) I picked two Caribbean cruises and headed to the New York Times Travel Show. After haggling with the competing cruise lines, I was offered the first cruise for $50 less than the best price I'd found online, and they threw in free trip insurance. In the end, I chose the second—$30 off with a free upgrade to a balcony stateroom—and truly got a bargain.

As a flight attendant, I'm always amazed by the stuff that people leave behind. Most of it never gets back to its rightful owner because there's no way of knowing who the owner is. To avoid misplacing your property, put things back into your carry-on after using them--never on the floor or in the seat-back pocket. Label important items like books or games with return address labels so they can be sent back to you if found.

If you plan to travel to a less-developed country, pack an extra suitcase with hand-me-downs of all sizes. Housekeepers and other resort workers make so little money that the clothes are greatly appreciated. On your way home, you can use that empty suitcase for souvenirs.

When my husband and I travel with our children, our luggage is weighed down by diapers, formula, and other necessities. To save space and hassle, we now ship ahead most of those items to our hotel. We also came across a Web site called babiestravellite.com, where we can order supplies and have them shipped anywhere in the world.

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.

My hearing loss once made it impossible to hear any alarm clock. Then I found the Shake Awake, an alarm clock that vibrates. I no longer stare at the ceiling all night prior to an early flight in fear of oversleeping. I clip Shake Awake to my pillow or place it on a hard surface near my bed, where its rattling definitely gets my attention.

When I go on a trip that requires me to accessorize a number of outfits, I buy little Ziploc bags and place the appropriate jewelry/panty hose/scarf inside. Then I punch a hole just big enough to slide the bag over the outfit's hanger. This way, my panty hose stay snag-free and my jewelry never gets misplaced.

I teach a Tulane University seminar on independent European travel for first-timers. Until recently, I advocated Europe's great rail networks as the way to go. Now, with the plethora of budget airlines, I recommend a combination of the two. But it makes the planning stage—which I find almost as much fun as actually taking the trip—more involved. Thank goodness for whichbudget.com, a Web site that lists, by city, which budget airlines serve which cities. Then, to find links to all of Europe's state railway Web sites, visit railfaneurope.net. Each site generally features a travel planner and, almost invariably, an English-language option.

If you plan to buy crafts in a country where bargaining is expected, use the time it takes for luggage to be unloaded to scope out the airport stores. Jot down items you like and their retail prices. If you find a similar item while touring the country, you have a top-end bargaining point. If you don't find the object at a better price, you can always pick it up at the airport while you're waiting for your flight home.

Tired of catching colds while traveling? Take along a travel-size package of Clorox wipes. Disinfect the tray table and armrests on the airplane, and the telephone and TV remote in your hotel room.

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.

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.
