New York: Harlem

If you book a package over the Internet, print out all the details of what's included and take it with you. When a hotel desk clerk in Paris said that the breakfast buffet we had enjoyed for the previous seven mornings was not included in our package, I was able to show him the printouts and prove him wrong. He apologized profusely and wiped the breakfast charges from our bill.

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.

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.

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.

In North American cities with large Chinese communities, choose a family-run Chinese restaurant and ask for the set family meals, usually written in Chinese. They are more authentic than those typically offered to tourists and people who are not Chinese—not to mention a better value. In San Francisco, for example, you can enjoy a five-course meal, which easily feeds a family of four, for less than $20.

Internet phone services like Vonage can be programmed to send transcribed voice mails to your email in-box. That way, you can check your home answering machine quickly at an Internet cafe without paying insane roaming fees on your cell. The transcriptions won't always be perfect, but you'll get the gist.

Before leaving for a vacation, I print out all our reservations and directions, and I create a contact sheet for emergencies. Then I gather all the papers together, punch some holes, and place them in a folder that has a middle section for three–holed papers. The side pockets hold brochures, business cards, ticket stubs, receipts, and maps that we collect along the way and want to bring home for our scrapbook.

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.

Instead of packing a complete shaving kit, my husband fills his wide-mouth Nalgene water bottle with items such as razors, spare contact lenses, eyeglasses, toothbrush, and so on. This turned out to be particularly useful on our trip to Costa Rica, where we also took the bottle on our day hikes to volcanoes and the jungle.

It helps to have a calculator if you plan to do a lot of shopping in foreign markets. When you find something you like, hand the seller the calculator and ask him to enter his best price. It's easy to convert the response into dollars so you know what you're spending. If necessary, the calculator can be used to haggle, especially if you don't speak the language.

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.

If you plan to leave a gratuity for hotel staff, follow our friend Phil's good advice: Give it at the beginning of your vacation, not at the end. He introduces himself to the housekeepers early in the trip and hands them a nice tip. Guess who always has plenty of coffee and fresh towels?

Love researching your destination online, but don't know how to organize all those printouts, maps, guidebooks, and tips? I get a 5 x 7" spiral notebook (Mead makes one with a sturdy cover and a pocket insert), a set of index tabs, and some glue. Divide the notebook into sections with the tabs (sights, maps, currency converter, restaurants, etc.). Photocopy—in reduction mode—all the info you want to bring, and glue it into the appropriate section. I leave plenty of pages for my journals. This creates an all-in-one personal guide that you can read again years after your trip!

Before my last long flight, I went to librivox.org and chose a bunch of books, short stories, and poems to download to my iPod--for free. The site has both adult and children's books, and the list is growing. All of the titles are in the public domain, and they're read by volunteers, so there's no question of copyright infringement. Even if you don't own an iPod, you can download them to your computer and burn them onto a CD.

If you're on a road trip with young children and you're looking for a place to let them blow off some steam, check out the playgrounds at local elementary schools. They almost always have equipment that your children will love to explore. It will also give everyone in the family a welcome chance to stretch their legs.

I switch from street shoes to flannel-lined moccasins at the airport. It saves time at the security checkpoint, and I'm comfortable during the flight. Once I land, I switch back to my street shoes.

If you make a hotel reservation online and then cancel online, print out and save the cancellation confirmation for at least two billing cycles past your trip. After our vacation, I found a "no-show" charge on my credit card for a room that I'd canceled well in advance. Without the confirmation, I had no way to contest the bill.

When I'm planning a trip, I almost always call the hotel concierge before I arrive, and if my hotel doesn't have one, I call a hotel that does. Recently, I asked for advice on what to see since I only had four days in a new city. I told the concierge what I thought I should try to do, and she said I had too many things packed into four days. She gave me a list of hot spots to visit and places to avoid, and even recommended a florist to call on for fresh flowers. With her help, my trip was far more enjoyable than it would have been otherwise.

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.

If you know you'll be cooking while on vacation, bring along small amounts of the spices you need for your favorite recipes. You'll save by not buying large containers of spices.

Before you go to sleep, check to see if a previous hotel guest left the alarm clock on. I've been awakened before 7 a.m. twice in the last couple of months by alarms I did not set. (Make sure the clock shows the right time, too!)

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.

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.

We were told by an airport security official to tape a business card onto the cover of our laptop. Turns out he has an average of six laptop computers left behind each day! There are so many more procedures now--removing shoes, removing coats--that people forget when they send their laptop through in a separate bin. The official added that it's very difficult to return them because most laptops have passwords that keep the owners' personal information hidden.

For overnight flights, pack a few Oral B Brush-Ups in your carry-on. Before the plane lands, you can "brush" your teeth, leaving you refreshed and ready for the day!

Use the shoeshine mitt often found in hotel bath- rooms to store your sunglasses. They fit nicely inside the pouch, and when you take them out, you have a soft material to clean them with. For extra protection while traveling, I store my sunglasses inside the shoe-shine mitt, fold the end closed, and then place it in my glasses case.

Priceline was a total pig in a poke for me, so I never used the web site, until I found out about biddingfortravel.com. This helpful Web site gives potential bidders an idea of prices that are being accepted (and declined) on priceline.com for particular dates and properties (or airfares or car rentals). I got the Hyatt Regency Miami for $35 per night because of this!

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).

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

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.
