Punta Cana: Penny-Wise in Paradise

Whenever I know I'll be renting a car, I pack a couple of folded paper towels and two small spray bottles--one filled with window cleaner and the other with Rain-X, a product that repels raindrops. It's hard enough driving an unfamiliar car in an unfamiliar location. At least with a clean windshield I'm able to see properly, no matter the weather.

When my husband and I visit places like India or Thailand, we pack only one extra change of clothes. When we arrive, we hit a local market and buy local attire--woven shirts, saris, sarongs, etc. Not only does this make packing easier, but we get a better cultural experience and end up with lots of wearable souvenirs!

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.

Before you book a room over the phone, peruse the hotel's site for its "Web only" rate. It's often cheaper than the best quote you'll get by calling. Recently, over the phone, I was quoted a daily rate of $129. I booked the same room online for $89.

If you plan to visit a theme park, always bring a few sandwich-size Ziploc bags. They'll protect your cell phone and wallet when you're riding on flumes and other water attractions.

Before setting off on one of my many backpacking excursions, I head to Kinko's to rebind my guidebook. I replace the cover with a plain black or navy one. It costs about $6 and allows me to blend in much better while traveling. People see my new book as a journal, not a travel guide that labels me a tourist.

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.

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.

Need a place for a laptop in your hotel room? Take the largest drawer from the bureau and put it upside down on the bed with the drawer front away from you. This creates a perfect-height desk for while you're sitting comfortably on the bed (you can even lean back on pillows), plus there's side space for papers, and the top leans toward you for easy typing or writing.

When I'm on a cruise with my wife's family and we're in a foreign city for the day, I get off the boat as soon as we dock and hail a taxi. I ask the driver to call his dispatcher and find me a van with an English-speaking driver. Then I negotiate an hourly rate and a pickup time at the dock. The family tours together for a few hours, and then each couple either gets dropped off where they want to spend extra time or returns to the boat (this is great for my elderly in-laws). We get a tailor-made city tour for a much cheaper rate than if we had booked through the cruise line.

I always bring a small flashlight to hotels in case there's a blackout. The building may not be equipped with emergency lighting, and, if necessary, my flashlight will help me quickly locate the nearest exit.

Here's an important tip for cruising in winter: Fly into the port a day or two before your ship is scheduled to depart. We booked a Costa Rican cruise but were stuck in New York, where all flights out of JFK airport were canceled. Itineraries that include stops in places with airports can allow people to catch up. Ours didn't.

The middle seat isn't always awful. On a recent trip overseas, I called too late to confirm an aisle or window seat. After explaining the plane's AB-CDEFG-HI configuration, the customer service agent urged me to take the very middle seat, E, because D and F have less foot room. (In some rows, there are metal boxes underneath the seats in front of you that house wiring for onboard electronics.) I went along with her advice somewhat skeptically, but I ended up with plenty of room. The people on either side of me weren't so lucky.

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.

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.

When seeking a cheap airfare, don't forget to consult the Web sites of the major charter tour operators--like Apple Vacations, TNT Vacations, Vacation Express, or SunTrips--which frequently sell air-only tickets in addition to air-and-hotel packages. Doing so helped me slash the cost of round-trip airfare to visit my mother in Las Vegas by well over 50 percent.

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.

If your vacation spot is a major port of call for cruise ships, plan excursions for the days that the ships aren't docked. Tours will be less crowded, and you'll get to see and do a lot more.

Easily packable, local specialty foods make great gifts for family and friends at home. At the huge Safeway in Kihei, Maui, we found a great selection of chocolate-covered macadamia nuts and Kona coffee beans in elegant gift boxes for far cheaper than in tourist-oriented shops. European grocery stores abound with gift ideas: British teas, French mustards and vinegars, and Italian olive oils are just a few examples. Just bear in mind that meats, produce, and other fresh items are a customs no-no.

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.

I always take a digital picture of the gas gauge to prove that I returned the rental car with a full tank. Some agencies try to charge for a minimal amount of gas when they "top off" the tank (which you're not supposed to do anyway). I've used these digital photographs to get refunds for gas charges that appeared on my credit-card bill after the fact.

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.

If you're traveling with someone, discuss a central meeting place in case you get separated. My husband and I were in Paris waiting to board the Metro. He was able to board the train, but I was left behind on the platform. Having a plan saved both time and needless anxiety.

Before you buy expensive bottled water from your hotel room minibar, head to the fitness center. You'll be able to fill up an empty bottle at the gym's water cooler or fountain for free, and you don't need to break a sweat.

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.

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!

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.

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.

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.

Before you leave the United States, photocopy receipts for any expensive items you're taking with you. This way, you won't have to argue with customs on the way home about declaring items you didn't buy abroad. (I'm a photographer, and I always bring expensive cameras on vacations.)
