If you don't have enough frequent-flier miles to get to Europe, use your miles to reach a major airport in the United States and then pay for the overseas flight from there. For a trip to Ireland, my husband and I used Delta SkyMiles to get from Cincinnati to New York's JFK airport and from there took Aer Lingus to Ireland. The Aer Lingus internet special was $267 per person. A Delta flight from Cincinnati to Ireland was $1,150 for two. We saved more than $600.

Some international airlines still give passengers a goody bag that includes a toothbrush, an eye mask, and socks for the flight. Keep those socks: They're handy when visiting temples in Thailand, Vietnam, and Cambodia, where you must remove your shoes before entering. I slipped on the socks and my feet stayed both clean and warm!

I reverse the batteries in my portable CD player before packing it in my suitcase or backpack, in case it's accidentally turned on when my bag is jostled. I came up with the idea after arriving at my destination to find that the brand-new batteries I'd put into my Walkman were dead.

To save space, pack items for travel that you can use in at least two ways. In a pinch, shampoo can double for detergent when washing your clothes (carry the bottle in a Ziploc bag in your suitcase); sandals or flip-flops also function as slippers; and a swimsuit cover-up can serve as a bathrobe.

A small compass is a great travel aid. Aside from the obvious benefits during country drives or hikes, it's extremely helpful in navigating winding city streets and orienting yourself once you exit a subway station.

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.

Ask your flight attendants for dining, lodging, shopping, and sightseeing advice. Most crews have up to the minute information gleaned from layovers, which they're more than happy to share with passengers. You can count on flight attendants to seek out budget treasures. I know—I've been married to one for more than 21 years!

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.

If you're traveling solo and want some company for dinner, try the sushi bar at a Japanese restaurant. It's a great place to meet locals. Plus, you'll receive extra attention and special recommendations from the chef.

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.

When my husband and I travel, we take at least three different credit cards. I carry one he doesn't have, he carries one I don't have, and we both bring our primary card. If one of us has our wallet stolen, we can cancel two cards and still have one to use. We each have different ATM cards, too--useful if a machine doesn't honor one of the cards, or if we need more cash than our daily limit allows.

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.

Don't be too quick to grab one of those GST tax-rebate envelopes that are everywhere in Canadian airports. The envelopes look official, but they're really from companies that process the request for you and often pocket 15 percent or more. Instead, go to the Canada Revenue Agency Web site (cra-arc.gc.ca), download the Application for Visitor Tax Refund, and then file the request yourself. Your check will arrive in a few weeks. Just remember to get your receipt stamped by the Canada Border Services Agency at the airport.

If the zipper on your luggage or your clothing is giving you any trouble, rubbing some lip balm or candle wax onto the teeth should loosen it.

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.

To feed a family of four in a very expensive tropical location like Anguilla or Bermuda (or most other Caribbean locations, for that matter), check to see if your hotel has phone books and look up the local pizza place. Nine times out of ten the pizza purveyors will deliver for free. You'll end up spending no more than $20 on pizza, bread sticks, and soda.

Bring a single-hole punch and lanyard on your next cruise. Once aboard, you can make a hole in your plastic key card and attach the lanyard, allowing you to carry the key around your neck. This is especially useful when your dress or slacks have no pockets. Just be sure to put the hole where it won't interfere with the card's magnetic strip.

If you can't sleep due to the heat in your non-air-conditioned hotel room, take a cold bottle of water and place it on your pillow, in the crook of your neck. It will cool your whole body down.

Even if you're not hungry when the flight attendant comes around with the snack service, take it for later. Although peanuts may not look appetizing at 7 a.m., they will look good later if you have nothing better to eat. And it saves you from picking up something at expensive airport shops.

On the final day of a recent Caribbean vacation, I tried to arrange for a late checkout, but was told it wasn't possible. The hotel offered me the use of a day room; it would have been perfect, but it was being used by other guests, and there was a very long wait for the shower. I went back upstairs and saw that someone was just about to clean my room. I told the housekeeper that I understood she had to do her job, but I wondered if I could I take a quick shower first. She offered to clean next door while I took my shower. I tipped her $10 and then left for the airport.

If you even manage to get a cell signal while at sea, your roaming charges will be outrageous. To communicate with your cabinmates, leave Post-it Notes on your door detailing where you'll be throughout the day.

I bought several items while in London and noticed when I returned home that my credit card number was printed in full on each sales slip. (In the United States, usually only the last four digits of the number are visible.) Travelers should be careful when using their credit cards overseas--don't leave the sales slips lying around.

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.

Know your PINs! My husband and I left home with very little cash on us, and instead of stopping to get money at the airport, my husband--ever the procrastinator--decided to wait until we got to Cancún to use his ATM card. Guess what? It didn't work in any of the machines. And although he had several credit cards for cash advances, he didn't know the PINs off the top of his head. We charged everything we could during our stay, but most of the markets don't take credit cards. Needless to say, I didn't come home with a lot of souvenirs.

While traveling, I love to send postcards to friends--and also to myself. I get the best photo postcard of the place I visited and write down what I did there as a reminder. When I get home, I tape them in my travel journals so I can flip back and forth between the photo and the reverie.

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.

Everyone knows that duct tape is great for helping out in travel emergencies, but no one wants to lug around a bulky roll of the stuff. By wrapping a few feet onto a pencil or ballpoint pen, you'll get a miniature roll that does not take up much in the way of additional space.

Pack a couple of mountaineering carabiners. Clip one through the handle or strap of your bag and secure it to something solid wherever you may be (to a bench in the park or in a train station, to the railing of an overhead compartment on a bus, etc.).The carabiner adds a bit of security, especially if you're snoozing.

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.

With two of our last three car rentals, the local branch wanted documentation beyond the standard insurance card issued by our insurance company. In San Juan, we were delayed a half hour while the agent made phone calls to verify that our liability insurance was good in Puerto Rico. In Miami, if we hadn't provided proof that our insurance covered rental cars, we would've been charged a daily collision insurance fee. Fortunately, we knew ahead of time and took a copy of the pertinent section of our policy. Our credit card included car rental insurance, but proof of that coverage was also required.
