A Rewarding Return to the Familiar

Disposable-camera lenses scratch just like any other lens would. Place a small piece of painter's tape (or another kind that won't stick too much) over the lens to protect it from contact with other items in your purse or backpack during travel.

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.

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.

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.

If you're traveling with a companion, pack half of your belongings in his or her suitcase and vice versa. This way, if one piece of luggage gets lost, you'll each still have some clothing.

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.

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.

Making international calls back to the States can be confusing if you're using a calling card and you're dialing a number by its catchphrase, such as CALL ATT. Obviously, many countries don't have the English alphabet on the telephone keypad. My solution? I create my own small keypads on a computer, print them out, and attach them inside my wallet, to my passport, and to my calling cards.

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.

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.

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.

Restrooms abroad rarely have hooks on stall doors. Our solution: Pack a small S hook in your shoulder bag and make use of a hole in the wall, a pipe, etc., to hang purses, jackets, or anything else you want to keep off the floor. S hooks can be found in most hardware stores, near the screws and bolts.

Before traveling by taxi in foreign (or even domestic) locations, ask a local (perhaps stopping in shops to question the sales staff) what the approximate taxi fare would be to a particular location. They've always been pleased to help me. In this manner, I can avoid paying the inflated tourist rates!

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

If you're divorced and plan to travel out of the country with your children, check the legal requirements in advance. When I tried to take my kids to Cancun, I learned too late that Mexico requires a notarized letter of consent signed by both parents for minors traveling alone or with one parent or guardian. If the parents are divorced, a copy of the parental custody agreement is allowed instead. The airlines enforce this rule before you get on the plane.

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.

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!

If your flight is canceled, don't just wait patiently in line to be booked on another flight; call the airline's 800 number. They'll answer your call faster, and you won't be waiting with other stranded passengers from that flight. (Or cover all bases by calling while in line.)

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.

Paper place mats can be useful anywhere there's an outdoor shower. By stepping onto a place mat after a bush shower in Botswana, I managed to keep my feet clean and avoided getting dirt in my clothes.

I work for a major airline and can attest to this tip for redirecting lost luggage. Place a copy of your itinerary--including contact info for where you're staying--inside your checked suitcase. If name and flight tags are missing, we'll still know where your bag needs to go.

Create your own postcards by writing on the back of photographs that you've taken and developed while still on your trip.

Even if you're not hungry when the flight attendant comes around with the snack service, take it for later. Although peanuts may not look appetizing at 7 a.m., they will look good later if you have nothing better to eat. And it saves you from picking up something at expensive airport shops.

My husband and I travel to out-of-the-way towns where rural roads can be hard to navigate. We use a handheld GPS (Global Positioning System) to mark the spot where we're staying, the main highway turnoffs, and, most important, the turns to unmarked side roads. When we're back-tracking and arrive again at confusing intersections, we whip out our GPS and immediately know which route to take home.

If the zipper on your luggage or your clothing is giving you any trouble, rubbing some lip balm or candle wax onto the teeth should loosen it.

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.

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.

When I'm planning a trip, I almost always call the hotel concierge before I arrive, and if my hotel doesn't have one, I call a hotel that does. Recently, I asked for advice on what to see since I only had four days in a new city. I told the concierge what I thought I should try to do, and she said I had too many things packed into four days. She gave me a list of hot spots to visit and places to avoid, and even recommended a florist to call on for fresh flowers. With her help, my trip was far more enjoyable than it would have been otherwise.

Certified scuba divers who take prescription medications should keep a doctor's permission-to-dive statement with their certification cards. On a recent trip to Jamaica, I truthfully completed a lengthy questionnaire about my health, revealing that I have medically controlled high blood pressure and cholesterol. I was told I could not dive without a doctor's OK, even though I exercise regularly, am very fit, and have no other health issues. I now carry a letter from my doctor attesting to my fitness for scuba diving.

My husband and I befriended some locals in Provence by joining them in a game of petanque. It was such a memorable experience that now we brush up on local games each time we plan to travel abroad. We've played dominoes in Spain and bocce in Italy.
