Road Trip: Florida's Best Thrift Stores on I-95

Some cruise lines offer discounts on a future sailing if you book it while on a current cruise. Back home, you can transfer the booking to your travel agent and work with them to try to lower the price even further. You'll be able to cancel your booking at no cost if you follow the cruise line's cancellation schedule. This is a great way to get some of your onboard expenses paid for in advance.

If you're a woman traveling alone, or your accommodations don't inspire confidence, simply wedge a small rubber doorstop at the base of the door when you're inside the room. It'll be virtually impossible to open the door from the outside.

If you're headed to a country that requires a visa, ask the consulate of that country, in the United States, whether visas are also issued at the airport there on arrival. In many cases (like Turkey and Egypt), they are. Obtaining the visa on arrival is a much simpler procedure and a real money-saver: You do not have to have photographs taken (they figure your passport already has a photo), you do not pay a hefty fee to the U.S.-situated consulate of the country, you avoid the expense and risk of mailing your passport to that consulate in advance of departure, and you avoid the expense of using a visa-acquiring company in the United States. But be sure the consulate is correct that the visa can easily be obtained on arrival.

I used to lug around a clothes steamer and adapter to stay wrinkle-free while on the road, but I've since opted for something more low-tech. I now travel with a Platypus collapsible bottle and a spray bottle head. After checking into my hotel, I immediately hang my clothes and give them a spritz with water from the spray bottle. After several hours, the wrinkles fall out, and the clothing is dry and ready to wear.

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.

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.

Want to visit museums with your children without the boredom and tears? Go to the gift shop first and buy postcards of the museum's most famous works. Have your kids treasure hunt for these masterpieces. When you get home the postcards can go right into your trip album.

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.

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!

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.

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.

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 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.

Before leaving on a trip, I print the names and addresses of my friends and family onto clear mailing labels. (All standard word-processing programs have preset templates for creating address labels.) Then, I take the address-label sheets with me on vacation. Since the addresses are already saved in my computer and the mailing labels are adhesive, addressing postcards has become really easy.

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.

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.

I was booking tickets online for an upcoming flight to Europe from the East Coast. One particularly attractive fare was offered on a U.S. airline as well as on its foreign "partner airline." Same plane, same flight, same base price. But it was more than $100 cheaper per ticket to book with the foreign airline versus the U.S.one. We saved more than $400 for four tickets, but we'll be on the same plane!

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're traveling with a companion, pack half of your belongings in his or her suitcase and vice versa. This way, if one piece of luggage gets lost, you'll each still have some clothing.

Whenever I'm in a country where drinking or brushing my teeth with the tap water is a risk, I cover the faucet handles in my hotel bathroom with a towel. As a result, I never accidentally turn on the faucet when I'm half asleep.

I travel with a mailing tube in my suitcase because I often buy paintings, drawings, and maps. My souvenirs always arrive home safe and sound. I just leave the mailing tube in my suitcase until the next trip.

While traveling abroad, I've frequently encountered some appallingly bad (and often very funny) English translations of menus. In those cases, I simply offered to clean up the translations in exchange for a meal. This has worked quite a few times.

Don't settle for the first answer to your travel question. If you need flight information, it's a good idea to phone the airline more than once and ask the same question. Recently, I wanted to see if I could fly standby on an earlier flight the same day. The first time I called, I was told that the earlier flight was booked. The second time, however, an agent said there were in fact seats available, and I could certainly fly standby. In the end, not only was I able to get on the flight, but I was upgraded to first class.

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.

Create an ID page for each of your children before you leave on a trip. In addition to vacation contact information (hotel name and phone number), include the child's name, a current photo, home address, phone, date of birth, Social Security number, passport number, hair color, eye color, height, any identifying marks, blood type, allergies, medications, doctor and insurance phone numbers and ID numbers, immunization schedule, and fingerprints (these don't change, so investing the time to have a set made is worth it). If the unspeakable happens, the ability to hand over instant, concise information to authorities may prove invaluable. Update it before every trip.

Don't assume a single room costs less than a double one. I booked a hotel in Spain online and noticed that rates were the same whether I booked a single or a double, but the single was much smaller and its bathroom had only a small shower stall and no tub.

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.

My husband cut an old contact lens case in two and uses the halves to carry his medication when we're traveling. He prefers them to regular pillboxes because lens cases are watertight and compact enough to carry inside a shirt pocket.

Public libraries in the ports of Alaska are a tremendous money-saver. Who wants to pay $5 a minute for Internet use from a cruise ship? During a port stop on a recent Alaska cruise, we found a city library that offered free Internet use for 15 to 30 minutes. Our only cost was a short wait in line.

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!
