Rent a Bike in Europe for Nearly Nothing

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.

When I called to book a hotel room in Budapest, I was offered a rate of $75 per night. After I told the concierge that I was looking for a room in the $35 range, he agreed to the lower price without much fuss. It sometimes pays to barter.

When I travel for business, I usually tack on a few extra days to do something active like hike in a nearby national park. I find that by taking two small suitcases instead of a single large one, I stay better organized and less burdened. I keep my business clothes, papers, and laptop in one bag and hiking clothes and gear in another. I leave the suitcase I'm not using at the time in the rental car and easily carry the lightweight case with the equipment and clothes I need into my hotel.

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.

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.

Download the most up-to-date airline schedules from the individual airline Web sites to your PDA before you leave home. Should you encounter a delay or cancellation at the airport, you'll have all the information needed to find another flight quickly.

Finding the bathroom in the middle of the night in a strange hotel room or cruise-ship cabin can be a challenge. Leaving the bathroom light on seems wasteful and makes the room too bright for sleeping. My husband and I used to travel with a night-light, but we couldn't always find a convenient place to plug it in. We've recently discovered a better solution: plastic light sticks. They come in several glow-in-the- dark colors and are activated by bending the tube into a circle and connecting the ends. Each evening, we hook one of the loops over the bathroom-door handle, where it provides a gentle glow through the night.

If you arrive in a foreign city after banking hours (and you can't use an ATM), convert only the money you'll need for the night. Some exchange booths offer a less favorable rate after banks close and then switch back to competitive rates when banks reopen.

The middle seat isn't always awful. On a recent trip overseas, I called too late to confirm an aisle or window seat. After explaining the plane's AB-CDEFG-HI configuration, the customer service agent urged me to take the very middle seat, E, because D and F have less foot room. (In some rows, there are metal boxes underneath the seats in front of you that house wiring for onboard electronics.) I went along with her advice somewhat skeptically, but I ended up with plenty of room. The people on either side of me weren't so lucky.

When not taking pictures, keep your memory card away from your camera. It's a simple method to ensure that any photographs you've shot will be safe even if your camera is stolen. My husband and I learned this lesson the hard way when we lost 250 shots of Kauai.

If you've accumulated more souvenirs on your trip than you can carry, drive your rental car up to curbside check-in, then return the vehicle and come back on the shuttle bus with only your carry-on. This only works if there's no check-in line, but can save dragging your luggage onto the shuttle bus, across parking lots, etc.

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.

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.

If you're planning to use an ATM abroad, make sure the money you need is in your checking account, because some foreign ATMs don't allow access to savings accounts. And remember to carry your bank's local phone number with you; 800 numbers generally don't work overseas.

Even if you're staying at a standard resort hotel, take advantage of the day passes sold by many all-inclusive resorts (i.e., the right to use their facilities--such as swimming pools and beach chairs--and enjoy their meals for a day). The passes are primarily designed for cruise passengers on day trips but can be obtained by anyone for very little money. For persons staying in a less-expensive, no-frills hotel, it can give you the experience of a larger, more extensive resort for a day or two.

Bungee cords make versatile travel accessories. They come in handy at the airport for lashing a duffel bag to a wheeled suitcase. They can be hooked together and used as a clothesline for swimsuits, towels, etc. On skiing trips, hook them onto ski boots to create carrying handles. While camping, use them to secure tarps, to suspend a lantern from a nearby tree limb, or to secure items in a canoe. They even hold your pants up if you misplace your belt.

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.

When I travel to a new city, I check with the local running club to see if there are any events planned during my stay. The entry fee is usually donated to a charity, and I get great exercise, meet locals, and tour a part of the city I may not have known about.

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.

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 dropping my laundry off at the front desk, I take a walk around the block and look for the nearest dry cleaner--probably the same one the hotel would've taken it to. By cutting out the middle man, I pay a quarter of what they charge at the hotel!

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.

During the hot months of summer, I plan to travel with a very small spray bottle. I'll fill it with water and use it as a mister to keep cool. I got this idea when we stayed at the Noga Hilton in Cannes. On the dresser was a pink aerosol can full of Evian water. I took it with us sightseeing and, wow, it was so refreshing to spritz water on our faces.

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.

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.

Using your frequent-flier miles, you might be able to visit two cities on one ticket. For example, my wife and I always trade in our Delta miles when we visit our daughters in Dallas and San Francisco. Because we have to fly through Dallas to get to San Francisco on Delta, we can stop over in Dallas for as long as we want before continuing on to San Francisco—and we use only one frequent-flier ticket each.

Finding healthy breakfast alternatives at an airport can prove difficult. I always travel with an insulated travel mug. Before leaving home I fill it with a high-protein cereal and then request low-fat milk on the flight.

I always try to work out before heading to the airport. It usually gets me tuckered out enough that I can relax and sleep on the plane. If I don't have time for pre-travel exercise, I take a brisk walk through the terminal before boarding or find a quiet spot in an empty gate for a little yoga.

In order to keep track of my bags, I use a small metal bell--the kind dancers from India wear on their ankles. I thread it with fishing line and tie it to my carry-on. If anyone touches my bag after I set it down, the bell chimes. It's not a very obtrusive sound, but it's distinctive enough for me to notice if a thief is trying to get into my things. The same bell can be hung on the doorknob inside your hotel room.
