Europe

Recycle the long plastic bags in which you receive your home-delivered newspapers. Slip your shoes into the bags before packing them in your suitcase.

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.

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.

When I'm on the road, I often have to use the hotel iron before heading out to business meetings. But getting water into the iron can be a hassle--most irons won't fit under the sink faucet, and using a glass to pour water into the tiny hole is nearly impossible without spilling everywhere. There's an easy solution: Use the carafe from the coffee maker. Just be sure the carafe is clean, or you could end up with coffee stains on your clothes.

Choosing a cabin is all about location, location, location. Check the ship's layout online before booking, and opt for a room with passenger floors above and below you. You don't want to try to sleep right under the disco, the casino, or the running track.

I take each of my grandchildren on a road trip the summer each turns twelve. The trips range in length from two weeks to a month and require careful packing. I've learned to put our clothes and any snack items we'll need in large plastic bins that fit in the back of my minivan. We each bring a small bag and pack it every evening with items we'll need for that night and the next day: no lugging heavy suitcases in and out of motels or hotels.

Cold-weather traveling means turning up the thermostat in your hotel room, and along with the artificially warmed air come dry skin and static electricity. Instead of turning on the heat, fill the bathtub with very hot water and leave the bathroom door open. In about an hour, your entire room will be warm and humidified.

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.

When planning a vacation, we send away for brochures from major tour operators. They provide hotel and restaurant recommendations and sightseeing itineraries, which we then duplicate on our own. Use this trick to mimic the vacation packages of high-end tour operators for what can turn out to be a fraction of the cost.

Once the hotel shampoo bottles I always seem to bring home are empty, I refill them with my own brand of shampoo, conditioner, and shower gel--instead of buying travel-size containers at the drugstore. I toss them, along with other small items (toothbrush, toothpaste, nail file, pillboxes, and a comb), into a medium-size Ziploc bag, and I'm ready to go; the clear plastic lets me find things easily.

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.

I was heading to the hotel ice machine when I noticed that our ice bucket was looking very tired and missing its disposable plastic liner. My solution: the shower cap that we never use anyway. In fact, it actually worked better than the liner bag because the elastic band held it in place around the top of the bucket.

On a trip to Molokai, the plane we were on was small, and luggage was crammed in every which way. At baggage claim, we noticed that someone had packed a bottle of Pine-Sol, and it had broken and leaked everywhere. Now we line our suitcases with garbage bags to protect our clothes—just in case. (It's also smart in case your bag gets left on the tarmac in a downpour.)

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.

Before I visit poorer countries, I pop into a thrift store and pick up some toys, stuffed animals, and an old suitcase or carryall. I try to avoid toys like Easter bunnies or Santas, which could be offensive, and expensive things that might embarrass parents. The contents of my extra bag bring joy to countless kids who have never had a thing.

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.

If I plan to travel to several countries that use different currencies, I pack a few cloth change purses: U.S. dollars go into one, British pounds in another, euros in a third, etc. When I'm sightseeing, I carry only the money I need; the purses that I'm not using are locked away in the hotel safe. I avoid fumbling around in shops and mixing up coins that look alike. Plus,I always know exactly how much cash I have.

When you're shopping for alcohol on any Caribbean island, ask if there's a Kmart nearby. Often the dis- counter is a short distance from the docks where the cruise ships tie up and has an extensive selection at prices lower than the liquor stores on the main drag. While you're there, pick up that extra roll of film or the sunscreen you forgot.

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.)

Going to a place where you don't speak the language? Take along a picture booklet filled with examples of common food items (chicken, cow, rice, bottled water, coffee, wine, etc.) and use it to find dishes you like—you only have to point to the picture of what you want. We did this during a recent trip to Asia and always had wonderful meals.

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.

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 find a reasonably priced villa or apartment to rent, try going directly to the owner through a site such as abritel.fr. (Click on the British flag for English.) I arranged to spend two weeks in an apartment in Brittany and one week in an apartment in the Loire Valley, all for a total of $800.

A bike tour will offer a good introduction to a place, and you'll cover much more ground than if you were on foot. In Buenos Aires, for example, Lan & Kramer Bike Tours (biketours.com.ar) has a few guided itineraries that are fun for all ages and abilities.

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.

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.

Don't save the best for the last day. If you wait until the end of your trip for "must-do" activities, you won't be able to reschedule if something unforeseen happens. I planned a snorkeling excursion for my final day in San Diego, but the waters were too rough, and the trip had to be canceled.

If you're traveling overseas, be sure to check the fine print concerning passports (go online or call the country's embassy). I had three months before my passport expired and found out at the last minute that I needed six months' leeway to enter Tahiti. Luckily, I was able to get a new passport just in time for my vacation.

After I fell into a stream in Cambodia, my digital camera wouldn't work. Someone suggested leaving the camera in a bag of rice overnight to draw out any condensation. By the next morning, it was dry and working perfectly.

Get the right maps. For road trips on the Continent, European maps are much more helpful when it comes to reading road signs. They'll say Napoli instead of Naples, Firenze rather than Florence. I could spend all day waiting for a road sign for Munich and miss the exit for Munchen.
