London: Clerkenwell & Environs

Before I embark on a trip, I cover the dirt of my potted plants with plastic bags after watering them well. (Cut a few slits in the bags and keep plants out of direct sunlight.) The soil will stay damp for about three weeks.

If you're even slightly tech savvy and have a cell phone that will work overseas, check with your service provider about the cost of text messages. Some carriers offer free incoming text messages, and several Internet search engines (Yahoo, MSN, etc.) will send free text-message "alerts" to your phone while you're away. Prior to your trip, log on and request that weather forecasts and news updates be sent to your number daily. Even if you never use your phone for costly overseas calls, you can receive up-to-the-minute information, in English, about your hometown or cities on your itinerary.

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.

Always carry peanut butter. A plastic jar is easy to pack, doesn't need refrigeration, is a great source of protein, and makes a quick, cheap meal when coupled with local bread. (But don't forget to pack a plastic knife for spreading it.)

Many tourist information offices provide discounted same-day booking services for local lodgings. My husband and I discovered this when we accidentally left a midweek gap in our travel plans between my husband's conference hotel and our B&B in Charleston. Instead of adding another night at either location, we stayed at one of the more elegant inns (normally over $200) for $70, courtesy of the Charleston Convention and Visitors Bureau.

On my first trip to Cancun, I noticed that my hotel room had a damp, musty odor. The next time I went, I brought two plug-in air fresheners: one for the bedroom and one for the bathroom. This helped tremendously. It was a pleasure to walk in and have a fresh-smelling room. Just make sure you have an adapter, if you need one.

Rather than risk losing your department-store credit cards and club-membership cards, you should really leave them behind when you go somewhere you won't need them. Your purse or wallet will be lighter and your worries fewer.

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 live in coastal Florida, where the electricity sometimes goes out during violent storms. Before a trip, I place a few ice cubes in a plastic bag and put the bag in the freezer. If the ice has melted and refrozen by the time I get home, I'll know we've had a power outage and that any food left in the refrigerator may be unsafe to consume.

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.

Bring your own linens. They're useful in a million different ways. Obviously a soft cotton pillowcase makes those scratchy airplane pillows bearable, but it can also be used to gather loose items when deplaning. A nice sheet will cover up an ugly bedspread or sofa, and makes a great tablecloth or picnic blanket.

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.

Want to visit museums with your children without the boredom and tears? Go to the gift shop first and buy postcards of the museum's most famous works. Have your kids treasure hunt for these masterpieces. When you get home the postcards can go right into your trip album.

Save major bucks by going onto eBay and purchasing coupons and gift certificates that others don't want or can't use for lodging, transportation, food, and admissions. I've found great discounts for airline and Amtrak tickets; car rentals; entrance to amusement parks such as SeaWorld, Disney, or Universal Studios; as well as overnights at many hotels. For example, I bought a $30 savings coupon at SeaWorld for only $1. Simply search for your destination and then type in "coupon" or "gift certificate."

Before you head to the airport, stop by the front desk of your hotel or cruise ship and ask if they'll print your boarding pass for you. It'll save Internet browsing fees and time at check-in. It's worked for me at several Marriott hotels and on a Celebrity cruise.

Don't put your magnetic sunglass clip-ons in the same pocket as your mass transit fare cards or hotel key cards. I managed to erase both my subway pass and my hotel key on a recent trip.

When you go to a convention or trade show, don't assume that the official prices at recommended hotels are the best you can do. Go to the hotel Web site. I recently got an AARP rate at a major hotel that was 30 percent below the special price offered through the tradeshow sponsors. AAA discounts often work, too.

Note the expiration dates of any debit or credit cards you plan on using while you're away. In Budapest, I tried to withdraw cash with my ATM card, only to find that it had expired just days before.

I've always traveled with a mini sewing kit in case I needed to sew on a loose button (or replace one).Now when I buy clothes, I just barely touch the end of a tube of Krazy Glue to the front of my buttons. Because they're covered by the glue, the threads don't fray as easily. No more lost buttons!

I have the words "hotel" and "taxi" on my cell- phone speed dial. On a trip, I change the numbers, but leave the preprogrammed titles the same--instant access and no more little slips of paper everywhere.

We all know to avoid drinking tap water in certain countries, but remember to forgo ice cubes, too. I've started bringing along two ice trays, which I fill with bottled water and freeze in my hotel room's mini-fridge.

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.

Quotetravelinsurance.com gives you comparable details on more than one hundred travel-insurance plans, enabling you to make the best buy. It relies on ratings from insurance industry overseers such as A.M. Best and state insurance commissioners before allowing an insurance company into its extensive lineup.

Every year, I get address labels from numerous charitable organizations. I keep them with me when traveling because it's the quickest way to provide my address to new friends, enter prize drawings at shops, sign guest books, etc. It's not only efficient; it can also help spread the word about worthwhile charities.

Traveling to non-English-speaking countries can be daunting for people with food allergies. Find someone fluent in the local language to write out what you are allergic to, the seriousness of the allergy (we had a friend include the phrase "this could kill me"), and what to do if you fall ill.

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.

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!

Put a few plastic trash bags in the outer pockets of your suitcases and carry-ons. If you arrive at your destination and it's raining, you can cover your luggage with the bags while you make your way to your hotel. Just cut a slit for handles or straps.

When you travel to a beach destination, bring your own snorkel gear. We bought snorkels, masks, and fins at home for half-off (at an end-of-summer sale) before a trip to Hawaii. They didn't take up much room in our luggage, and we would have spent as much or more renting the equipment.

My friends and I contribute to a kitty and use that money to pay for group expenses such as taxis and meals. It saves us from having to figure out each person's share at every stop. At the end of the trip, we split what remains.
