Nonstop Mexico

I reverse the batteries in my portable CD player before packing it in my suitcase or backpack, in case it's accidentally turned on when my bag is jostled. I came up with the idea after arriving at my destination to find that the brand-new batteries I'd put into my Walkman were dead.

Pack a power strip and extension cord for your next cruise. Many cruise-ship cabins have only one out- let, but you'll definitely need more if you want to power up your laptop, iPod, cell phone, electric razor, hairdryer, or any other gadgets you bring on board.

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 buying bottled water, look at the bottle cap to see if the seal is still intact. While visiting the Acropolis on a very hot day this summer, I caught a young boy refilling empty water bottles from a tap and recapping them. He was then selling the bottles to thirsty tourists.

At a theme park, tie a brightly colored scarf to the handle of your stroller before you enter a ride. When you return, you'll be able to quickly pick out your stroller from a sea of look-alikes.

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!

When not taking pictures, keep your memory card away from your camera. It's a simple method to ensure that any photographs you've shot will be safe even if your camera is stolen. My husband and I learned this lesson the hard way when we lost 250 shots of Kauai.

On international flights, I used to fumble through my belongings--often having to retrieve them from the overhead bin--after a flight attendant appeared with customs and immigration forms. (I don't know of many people who have their passport's number and date of issue memorized.) Now I write all that info on the bookmark of whatever I plan to read on the long flight so I don't have to dig out my passport. I can fill out the card quickly--giving me more time to loan my pen to all the people who never seem to carry one.

If you even manage to get a cell signal while at sea, your roaming charges will be outrageous. To communicate with your cabinmates, leave Post-it Notes on your door detailing where you'll be throughout the day.

Finding healthy breakfast alternatives at an airport can prove difficult. I always travel with an insulated travel mug. Before leaving home I fill it with a high-protein cereal and then request low-fat milk on the flight.

By the time I got home from my first trip to Europe in 1963, I'd collected menus from several restaurants I liked. I threw them into a box. In 1988, I returned to Europe and went to the Middle East. Once again, I picked up a few menus. This time I had them all framed and they now hang in my kitchen. Since then, I've added to the collection. It's fun looking at the prices and remembering the good times—plus they make great conversation pieces when I have a party.

Pack a glue stick for journaling. Rather than bringing home an envelope full of ticket stubs and mementos, you can glue them into your journal as you're traveling. You'll have a better chance of remembering what the ticket was for if you label it right away.

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.

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.

If you don't have enough frequent-flier miles to get to Europe, use your miles to reach a major airport in the United States and then pay for the overseas flight from there. For a trip to Ireland, my husband and I used Delta SkyMiles to get from Cincinnati to New York's JFK airport and from there took Aer Lingus to Ireland. The Aer Lingus internet special was $267 per person. A Delta flight from Cincinnati to Ireland was $1,150 for two. We saved more than $600.

Try to book the first flight out in the morning, because those planes often arrive at the airport the evening before. You won't have to rely on an incoming plane, which could be delayed or canceled due to bad weather elsewhere, resulting in your own flight being delayed or canceled.

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.

When traveling in the developing world, I always bring several packets of stickers to give to children. They're wonderful icebreakers.

Online check-in isn't just for airlines. After reserving an Alamo car over the Internet, I was offered online check-in just by entering my credit card number and driver's license information for approval. At the airport, following Alamo's instructions, I informed the shuttle-bus driver that I had checked in online and reserved an economy car. I was dropped off in the lot and told to pick whichever car I wanted. I drove it to the exit, where my credit card and driver's license were verified on the computer, and I was done.

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.

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.

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.

The help of a concierge at an expensive hotel is available even if you're staying at a motel across the street. Go to the concierge with $5 (or whatever the assistance is worth to you) held discreetly but visibly in your hand. Chances are you won't be asked whether you're staying at the hotel. This worked for us once when we were stranded by a blizzard. We tried to rebook our flights on our own, but phones at the airlines were busy for two days straight. The concierge at a fancy hotel a few blocks away got through on his first try and managed to rearrange our flights for us.

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.

I always snap photographs of scenic highway markers, park entrance signs, and the like. These informational photos are put into our album to help identify the many sites that we visited.

Just before I go through airport security, to save time and to avoid leaving something important behind, I collect all loose items--change, money clip, belt buckle, pens--in a large Ziploc bag. I send the bag through the X-ray machine with the rest of my luggage. After picking it up at the other end, I put the things back in place and either toss the bag or keep it for the return trip.

There's nothing worse than trying to fall asleep under a mosquito net and then realizing that the bugs are finding a way inside. So next time you're heading someplace tropical--where you know you'll be sleeping under mosquito netting--remember to toss a roll of Scotch tape into your suitcase. It's perfect for quick repairs.

Pay close attention to those newsletters enclosed in your frequent-flier statements. They usually contain special offers and promotions that can earn you double or triple miles if you stay at a certain hotel or eat at a certain restaurant.

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!

Sign up for guest programs at every hotel chain that offers one, even if you haven't stayed at that hotel before or think you may not travel enough to reap benefits from multiple stays. Some programs send coupons for discounted rooms or complimentary room upgrades just for being a member. After signing up for the Omni Hotels Select Guest program, I received a coupon that I was able to redeem for a room in Chicago for $80 per night.
