An Excerpt from "Fruit of the Lemon"

I prefer laminated city maps because I can circle all the things I want to see in a given day with a dark erasable marker. Once I have everything marked, I plan my route and start walking. The next day, I erase the previous day's marks and begin all over again.

My daughter and I bought disposable digital camcorders at a CVS pharmacy before going to Europe. It was a nice way to document our trip--each camera stored about 20 minutes of video. Once home, we dropped the cameras off at the pharmacy. The next day, our DVD was ready. We were very pleased with the quality and the cost: $30 for the camera and $13 for each DVD.

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.

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.

I've saved lots of money using AAA. In addition to providing excellent roadside services (help with stalled cars, lost keys, etc.), most AAA chapters offer discounted tickets to Disney World and a preferred parking pass that enables you to grab specially designated spots near the entrances. It's a dollar saver, and you don't have to walk far or take the trolley in the parks!

I agree that the anti-seasickness medication for cruises, Bonine, is excellent and effective; but there is a budget way to buy it. The primary ingredient in Bonine is meclizine (25 mg). While a package of eight Bonine tablets costs just over $4 at a drugstore, you can buy a bottle of 100 generic meclizine (25 mg) for about the same price. This is an over-the-counter (no prescription needed) item, but you usually have to ask for it at the pharmacy counter.

A padlocked zipper tells thieves there's something in your bag worth stealing, but a key ring is much less obvious. Just use it to latch together the zippers. Best of all, you'll never have to worry about forgetting your combination.

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.

For fire-safety reasons, cabins don't have their own irons. Don't wait until the last minute to tackle your evening wardrobe. You can find shared irons down the hall in the laundry room, but lines often form before mealtimes. Opt for off-hours (like mornings).

Check out worldclimate.com to find monthly average temperatures and rainfall for thousands of cities worldwide. You can avoid countries during their rainy seasons, and the information is useful for figuring out what to pack.

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.

Before you head to the airport, make a list of all the items in your checked luggage that would be prohibited in your carry-on. If an item (such as a knife for a picnic) makes its way into your purse or daypack during your travels, it should be accounted for when repacking and put into the checked piece to avoid hassles at airport security.

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.

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.

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 carry bilingual takeout menus when traveling to countries like China, Korea, and Vietnam. When I'm at a restaurant with no menu (or one that I can't read), I give mine to the waiter so he can point to dishes they can prepare. I've learned to pack a few extra menus, as the restaurants often like to keep a copy.

I've created files--some general (Southeast Asia), some specific (Hawaii)--for articles and clippings about places I'd like to visit in the future. I don't want all the good tips, restaurant recommendations, and out-of-the-ordinary itineraries to go to waste just because I'm not planning an immediate trip. The files don't have to be super organized--just throw in the clippings, and you can weed through them later. You'll be glad you have the information when you do get a chance to go away.

I carry recipe cards with me to jot down interesting dishes I come across while on vacation. (I also like to use colorful postcards from the area I'm visiting and trim them to fit my recipe box.) Here's a wonderful dessert idea I brought home after spending a rainy afternoon with my husband in a London pub: Top a warm waffle with vanilla ice cream, maple syrup, and chopped pecans. It's heaven with a cup of hot tea.

I never leave home without dental floss. I've used it as a clothesline between tents in Botswana's Okavango Delta and to replace a lost screw for my sunglasses in Malaysia. I even cut off a piece of floss the size of my waist and headed to the night markets in Bangkok. My "tape measure" assured a perfect fit!

Check out grocery stores in Europe for bargains on wine. On our last trip to Italy, I found a 1993 Banfi Brunello in a small market for $16. If I could find it at all in my local wine shop, that same bottle would cost more than $100. I only wish I had listened to my husband and bought all three of the bottles the store had.

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.

Don't rush off the car-rental lot. Before driving away--especially in foreign countries where the controls might be unfamiliar-test the headlights and brakes, and look for the extra tire and changing tools. I once had a rental with malfunctioning brakes in Mexico and caused a minor accident--one that could certainly have been avoided had I checked them properly before leaving the lot.

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.

Public libraries in the ports of Alaska are a tremendous money-saver. Who wants to pay $5 a minute for Internet use from a cruise ship? During a port stop on a recent Alaska cruise, we found a city library that offered free Internet use for 15 to 30 minutes. Our only cost was a short wait in line.

In Europe, my husband and I like to use public transportation. As a result, we frequently find ourselves studying itineraries displayed on train station walls, trying to read schedules posted at bus stops, or staring at kiosk-size town maps. On our last trip, my husband snapped digital photographs of those things. We were able to take the map or itinerary with us and could refer to it as needed by using the zoom feature.

It's unnecessary to make a packing list for each trip. Instead, draw up a master list with everything you might need on any given trip--from ski goggles to snorkels, slippers to saline solution. Save it on your computer. Before you start packing, cross out anything you don't need for that particular trip.

When you change your clocks back or forward, be sure to check the expiration date on all your frequent-flier miles. This way they're checked twice a year. We overlooked one of the many accounts in our household and lost a free ticket when the miles expired.

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.

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.

Before traveling overseas, look at your health insurance card. If it only shows an 800 or 888 number for precertification of hospital admissions, call that number and obtain the local number with an area code. Many 800 numbers can't be dialed from foreign countries. I learned this the hard way during an emergency hospital admission in Switzerland. The delay in reaching my carrier could have been avoided.
