USA and Canada

Place a coin over the veins on the inside of your wrist (about two finger widths from the base of your palm) and secure it in place with a rubber band or ponytail holder. The gentle pressure of the coin will stimulate nerves that control nausea, just like the motion-sickness bands that are sold at drugstores.

Disposable-camera lenses scratch just like any other lens would. Place a small piece of painter's tape (or another kind that won't stick too much) over the lens to protect it from contact with other items in your purse or backpack during travel.

Carry the exact change for public transportation. In Venice, we were annoyed when a vaporetto (water taxi) ticket-taker refused to give us our change. Later, we discovered that if you don't have the exact fare, ticket agents make no promises about giving change.

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!)

We've noticed that when booking a flight for our family under one reservation, some airlines will only credit the 1,500 bonus miles (500 for booking online, 500 each way for printing boarding passes) to the person whose name the reservation is under. This is regardless of whether the other family members have mileage accounts. To avoid this, make a separate reservation for each of your family members and then pick seats together.

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.

If you get lost on a ship, remember that most share a common layout. The lido-deck buffet restaurant, for example, will almost always be in the back to accommodate comfortable outdoor seating in the least windy part of the ship, while the lounge/theater will be in the front because wind is not a factor (there are no windows).

Pack a glue stick for journaling. Rather than bringing home an envelope full of ticket stubs and mementos, you can glue them into your journal as you're traveling. You'll have a better chance of remembering what the ticket was for if you label it right away.

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.

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 unpacked a pair of black slacks recently to find them covered with white fuzz. I didn't have a lint brush handy, so I used the luggage sticker from my bag--the gummy side took the lint right off.

Place a fabric softener sheet in your suitcase when packing. It'll absorb odors and dampness and keep clothing smelling fresh. It's most beneficial in warm, humid climates and while at sea. I found this quite useful during my twenty-three years in the U.S.Navy.

Before traveling to any city, do a search on the Internet of the city name and the word "coupon" ("New Orleans coupon"). You will find many sites offering two-for-one, percentage-off, and dollar-off discounts. On a recent trip to St.Louis, we saved $100 at restaurants and attractions.

Save the flip-flops you're given at the nail salon after a pedicure. They make great shower shoes. They're lightweight and dry quickly, and you can throw them away at the end of your trip.

I find that hotel bathrooms rarely have enough hangers and hooks for clothes and wet towels, so I always bring a few snap-lock suction hooks. (They function better than regular suction hooks because they're more secure and are therefore able to hold heavier items.) It's always nice to have a place to hang a bathrobe.

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.

About a month before leaving on vacation, I start clipping the crossword puzzles from the daily newspaper and pasting them into a blank notebook. The puzzles keep me occupied during my trip. The newspaper's crosswords are so much more interesting than the generic books of them you can purchase at the airport.

After looking for years for the perfect toiletries bag and being frustrated by many that were less than ideal, I finally discovered one that is just right: a soft-sided lunch box I bought at the supermarket. It has an outer zipped pocket with small compartments and slots perfect for often-used items like a toothbrush and toothpaste. There's a small removable zipper pouch inside (meant for a small ice pack) for those smaller, hard-to-find items like nail files and pill bottles. The remaining space inside is just right for larger items like shampoo and hand lotion. Other helpful features include both a small handle and shoulder strap and a waterproof, easy-to-clean interior. As an elementary school teacher, I know firsthand that it'll last: It was designed to withstand daily use by kids!

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.

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.

When on vacation, I split my cash into envelopes, one per day, so I can keep track of how much I'm spending. If I need to dig into the next day's cash, I'll know that I've overdone it, and if I want to stay on budget, I'll have to cut back the next day. Any money left at the end of the day goes into a separate envelope. I've actually come home with money this way!

I always pack a Petzl Tikka Plus headlamp. It's small, weighs next to nothing, and is perfect for reading in bed at night without disturbing my husband. They're sold online and at outdoor-gear stores for about $33.

After I was unable to locate any awards seats online for a wide selection of days and routes, I called the airline. An agent told me that the airline's Web site isn't allowed to book awards seats for its partner airlines, but agents can. Within minutes, I had enough options that I found it difficult to make a decision.

Put toys within kids' reach on road trips. Hang a shoe organizer on the back of the passenger seat so children can keep stuffed animals, books, and games organized in the pockets. Having everything close at hand may help prevent meltdowns along the way.

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!

During a visit to Mexico City, I was sitting in a plaza near a fountain, watching the locals stroll around in their Sunday best. Nearby, an older gentleman was playing a concertina; his music perfectly framed the scene. I took lots of pictures, but I didn't have a way to capture that music. Now I pack a small tape recorder along with my camera.

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.

Restrooms abroad rarely have hooks on stall doors. Our solution: Pack a small S hook in your shoulder bag and make use of a hole in the wall, a pipe, etc., to hang purses, jackets, or anything else you want to keep off the floor. S hooks can be found in most hardware stores, near the screws and bolts.

Driving around Italy last summer, my husband and I found that even the most detailed maps left us scratching our heads in confusion. Desperate and lost, we decided to follow a tour bus. Guess what? It got us exactly where we wanted to go.

It can be difficult for parents to find a place to bathe their infant while on vacation. Showers obviously won't work, and the miniscule sinks generally found in hotel bathrooms aren't appropriate either. On our last cruise, we eliminated the whole problem by packing a small, inexpensive inflatable bathtub. (Ours cost only $7.99.) When we arrived, we blew it up and placed it in the bottom of the shower for an instant, safe baby bath.
