Baby Steps to Save the Earth

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.

Put your perfume and cologne bottles inside pairs of rolled-up socks to keep them cushioned during your journey.

Don't save the best for the last day. If you wait until the end of your trip for "must-do" activities, you won't be able to reschedule if something unforeseen happens. I planned a snorkeling excursion for my final day in San Diego, but the waters were too rough, and the trip had to be canceled.

If you go directly from the air-conditioned ship out onto the open-air deck (which is usually warmer and more humid in most cruise destinations), your camera's lens is likely to fog up. Warm the camera with your cabin's hairdryer on a low setting or briefly leave it out on your balcony so it can acclimate to the weather.

My husband and I travel to out-of-the-way towns where rural roads can be hard to navigate. We use a handheld GPS (Global Positioning System) to mark the spot where we're staying, the main highway turnoffs, and, most important, the turns to unmarked side roads. When we're back-tracking and arrive again at confusing intersections, we whip out our GPS and immediately know which route to take home.

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.

Don't assume you can save a spot at the pool with your towel. Cruise lines give you one pool towel at the start of the cruise. If you don't have it (or a cleaned trade-in) at the end, you'll get charged. If you let it out of your sight, you run the risk of losing it or having it stolen by a fellow cruiser.

Having spent a number of years working for Norwegian Cruise Line, I learned that a dinner roll helps to settle the stomach when seas become rough. The less liquid sloshing around unimpeded, the better. And if you forget your motion-sickness pills or wristbands, fear not, as the purser always has medicine available for seasick passengers.

Frequent fliers should consider noise-cancellation headphones. They have a built-in device that "hears" low-frequency sound just before you do and generates a sound wave that cancels it out. Several manufacturers make them, ranging in price from $40 to $300 or so.

The help of a concierge at an expensive hotel is available even if you're staying at a motel across the street. Go to the concierge with $5 (or whatever the assistance is worth to you) held discreetly but visibly in your hand. Chances are you won't be asked whether you're staying at the hotel. This worked for us once when we were stranded by a blizzard. We tried to rebook our flights on our own, but phones at the airlines were busy for two days straight. The concierge at a fancy hotel a few blocks away got through on his first try and managed to rearrange our flights for us.

Before exchanging foreign currency at the airport, find out if there's a departure tax. At the Bangkok airport, we were very upset- as were travelers around us- to find we had to pay a fee before continuing to our gate. Unfortunately, by that point everyone had cashed in their baht, so the options were a conveniently located ATM, a credit card, or an exchange booth with notably poor rates. When we described this incident to friends, they told us of a similar experience when trying to leave the Dominican Republic.

Many computer photo albums use camera date stamps to organize collections. Whenever you're traveling in a time zone that might affect the date stamp (if you're crossing the International Date Line, for example), remember to reset your camera's clock.

I prefer laminated city maps because I can circle all the things I want to see in a given day with a dark erasable marker. Once I have everything marked, I plan my route and start walking. The next day, I erase the previous day's marks and begin all over again.

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 never leave home without dental floss. I've used it as a clothesline between tents in Botswana's Okavango Delta and to replace a lost screw for my sunglasses in Malaysia. I even cut off a piece of floss the size of my waist and headed to the night markets in Bangkok. My "tape measure" assured a perfect fit!

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.

Get the right maps. For road trips on the Continent, European maps are much more helpful when it comes to reading road signs. They'll say Napoli instead of Naples, Firenze rather than Florence. I could spend all day waiting for a road sign for Munich and miss the exit for Munchen.

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.

Ziploc now makes extra-large bags with handles. They're nearly two feet by two feet, and although Ziploc advertises them as being good for storage, they're also useful for traveling. Bring one on long shopping excursions and then use it as an extra carry-on for souvenirs on the way home.

Treat yourself to a golf-ball foot massage. During a long flight, or afterward in your hotel room, take off your shoes, put a golf ball on the floor, and roll it under your foot. It's a great stress reliever. Practice a bit before you try it on a plane, so that your ball doesn't go rolling down the cabin, tripping up unsuspecting passengers.

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!

Paramedics now look for emergency contact information in victims' mobile phones. Store the word "ICE" (In Case of Emergency) in your address book, along with the name and number of the person you'd like emergency personnel to call on your behalf. (For more than one entry, use ICE1, ICE2, etc.) Tell your friends or family members that you've chosen them as your contacts and make sure they're aware of any medical conditions or allergies that could affect your treatment.

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.

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.

I use an inexpensive, thumb-size USB flash drive to store medical and insurance contacts, confirmation codes, credit card numbers, addresses, and phone numbers. It fits in a secure zip pocket in my travel purse. If I don't have my laptop, I can insert the flash drive in most hotel or Internet café computers. Some USB flash drives password-protect your data, or you can download a free encryption program.

Preserve even the small number of frequent-flier miles you may obtain by making occasional use of a particular carrier; the miles can be worth money. Even if you don't regularly fly on Delta, Northwest, Continental, or several other airlines, sign up for their frequent-flier programs when you book a long or overseas flight. Points.com allows you to redeem miles for magazine subscriptions, music downloads, and other products. You can also use miles to get small discounts on purchases at retailers such as Amazon.com.

If you're stranded overnight at an airport and receive a "distress rate" voucher, call the hotel of your choice before blindly following the airline's suggestion. You may find that for that discounted rate (or a few bucks more) you can stay in a hotel with a lot more amenities than the one the airline would put you in. After a long, mishap-filled trip, anyone can appreciate a really good mattress, a top-notch restaurant, and an indoor swimming pool.

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.

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.)

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.
