Costa Rica Eco-Trip

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.

When I travel with friends, we decide ahead of time who's going to bring what. If we're sharing a suite or have adjoining rooms, we don't need multiple hair dryers and umpteen bottles of shampoo. With the weight limits on baggage, we'll need the extra space in our suitcases for souvenirs!

It's often cheaper to buy a ticket to London and then fly onward within Europe via a regional low cost airline. Last summer, my husband and I bought consolidator tickets to London for $397. From there, we flew EasyJet to Nice for $72. The total cost was $469—much less than flying directly to Nice, plus we enjoyed a stopover in London.

My husband and I always travel around Europe by train. When we arrive in any city, we first stop at a ticket window and get all the information we'll need for the next leg of our journey. This gives us plenty of time to find an English-speaking ticket agent who'll print out departure times and platform numbers for us. Before leaving the station, we can note the location of the platform we'll be looking for that morning. One wrong move when you're rushing for a train and you could end up in the wrong city!

Try getting a discount on your hotel room by offering to pay in cash. A hotel reservationist suggested this approach when I phoned to reserve at a hotel in London. I asked if the hotel could grant a discount based on my AARP or AAA membership, as many hotels do in the United States. Her response was that the only discount she was able to offer was 10 percent if I paid in cash.

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.

I always take a digital picture of the gas gauge to prove that I returned the rental car with a full tank. Some agencies try to charge for a minimal amount of gas when they "top off" the tank (which you're not supposed to do anyway). I've used these digital photographs to get refunds for gas charges that appeared on my credit-card bill after the fact.

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.

If you're traveling with someone, discuss a central meeting place in case you get separated. My husband and I were in Paris waiting to board the Metro. He was able to board the train, but I was left behind on the platform. Having a plan saved both time and needless anxiety.

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.

Using restaurant.com, you can buy gift certificates good at eateries in your destination city, regularly snagging (in my experience) $25 certificates for as little as $5 to $8.The site is awesome, and it works as well for restaurant certificates in your own city and for obtaining gifts for friends.

Tell me I'm not alone: Almost every time I park my car at the airport, I have trouble finding it when I return. (I even reported my car stolen once after searching for hours, only to discover I was in the wrong lot!) I now use my cell phone to leave myself a message as to where I've parked my car.

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.

Before traveling by taxi in foreign (or even domestic) locations, ask a local (perhaps stopping in shops to question the sales staff) what the approximate taxi fare would be to a particular location. They've always been pleased to help me. In this manner, I can avoid paying the inflated tourist rates!

Certified scuba divers who take prescription medications should keep a doctor's permission-to-dive statement with their certification cards. On a recent trip to Jamaica, I truthfully completed a lengthy questionnaire about my health, revealing that I have medically controlled high blood pressure and cholesterol. I was told I could not dive without a doctor's OK, even though I exercise regularly, am very fit, and have no other health issues. I now carry a letter from my doctor attesting to my fitness for scuba diving.

If the porters haven't delivered your luggage to your door by the first night of the cruise, check what our experts call the "naughty room." Security will store any bags containing contraband (like candles, alcohol, or coffeemakers) in this centralized location until you come claim it. You'll be able to pick up your bag on the first night, but banned items will not be returned until the end of the trip.

Sign up for guest programs at every hotel chain that offers one, even if you haven't stayed at that hotel before or think you may not travel enough to reap benefits from multiple stays. Some programs send coupons for discounted rooms or complimentary room upgrades just for being a member. After signing up for the Omni Hotels Select Guest program, I received a coupon that I was able to redeem for a room in Chicago for $80 per night.

You can suspend more than your newspaper when you're away. On several occasions, DirecTV has agreed to put my account on hold while I was traveling--without penalties, additional fees, reconnection charges, or the like. So, instead of a monthly bill of $65, mine gets prorated.

Check out worldclimate.com to find monthly average temperatures and rainfall for thousands of cities worldwide. You can avoid countries during their rainy seasons, and the information is useful for figuring out what to pack.

If you're even slightly tech savvy and have a cell phone that will work overseas, check with your service provider about the cost of text messages. Some carriers offer free incoming text messages, and several Internet search engines (Yahoo, MSN, etc.) will send free text-message "alerts" to your phone while you're away. Prior to your trip, log on and request that weather forecasts and news updates be sent to your number daily. Even if you never use your phone for costly overseas calls, you can receive up-to-the-minute information, in English, about your hometown or cities on your itinerary.

In order to provide any reimbursement for a lost suitcase, most airlines and insurance companies require an itemized list of exactly what was inside it. Unfortunately, remembering everything you packed after the fact is virtually impossible. To avoid the headache, take pictures of the items you're going to put in your suitcase with your digital camera or cell phone. The photos will make creating the list a breeze, and, in the event of a dispute with the airline or insurance agent, you have some visual evidence of ownership.

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.

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.)

My friends and I contribute to a kitty and use that money to pay for group expenses such as taxis and meals. It saves us from having to figure out each person's share at every stop. At the end of the trip, we split what remains.

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.

Note the expiration dates of any debit or credit cards you plan on using while you're away. In Budapest, I tried to withdraw cash with my ATM card, only to find that it had expired just days before.

When my husband and I visit places like India or Thailand, we pack only one extra change of clothes. When we arrive, we hit a local market and buy local attire--woven shirts, saris, sarongs, etc. Not only does this make packing easier, but we get a better cultural experience and end up with lots of wearable souvenirs!

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.

A company called Orikaso makes brightly colored polypropylene sheets that can be folded--kind of like origami--to form a dish, bowl, or cup. The sheets are lightweight and reusable, and you simply flatten them when you're finished. We found ours at a sporting goods store, but you can also buy them online. Check orikaso.com for retailers.

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.
