12 Mysterious Underground Tours

Play Let's Make a Deal when you're shopping for vacations at travel shows or expos. Go armed with your own research and a credit card.(You're likely to get a better price if you know what the vacation is worth, and if you're willing to buy it on the spot.) I picked two Caribbean cruises and headed to the New York Times Travel Show. After haggling with the competing cruise lines, I was offered the first cruise for $50 less than the best price I'd found online, and they threw in free trip insurance. In the end, I chose the second—$30 off with a free upgrade to a balcony stateroom—and truly got a bargain.

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 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 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.

Paper place mats can be useful anywhere there's an outdoor shower. By stepping onto a place mat after a bush shower in Botswana, I managed to keep my feet clean and avoided getting dirt in my clothes.

About a month before leaving on vacation, I start clipping the crossword puzzles from the daily newspaper and pasting them into a blank notebook. The puzzles keep me occupied during my trip. The newspaper's crosswords are so much more interesting than the generic books of them you can purchase at the airport.

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.

When looking for the lowest airfare, I've found that in some cases the best rates pop up when searching for one traveler instead of two. Recently, I wanted to buy one-way tickets from New York to Orlando for two people and came up with $87 per person. But when I selected one traveler, the fare dropped to $72.

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.

Here's an important tip for cruising in winter: Fly into the port a day or two before your ship is scheduled to depart. We booked a Costa Rican cruise but were stuck in New York, where all flights out of JFK airport were canceled. Itineraries that include stops in places with airports can allow people to catch up. Ours didn't.

I travel with two cameras: a digital SLR for the majority of my shots, and a small disposable camera for when I ask strangers to take pictures of me. As much as I tend to trust other people, I'm not ready to hand over my $1,000 camera to someone I don't know at all.

Before booking your next ski trip or reserving a table for dinner, find out what your credit card company has to offer. American Express sometimes has discounts on lift tickets; MasterCard has offered buy-one-get-one-free at local restaurants; and Discover Card has access to deals to Universal Studios. Check out americanexpress.com/offerzone, mastercard.com (be sure to click on Promotions), and discovercard.com.

By starting a blog for each trip--at blogger.com, among others--you can keep your friends and family up-to-date on your adventures. All you need is an Internet café to add entries and photos while you're on the road.

When traveling in the developing world, I always bring several packets of stickers to give to children. They're wonderful icebreakers.

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.

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.

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.

Once the hotel shampoo bottles I always seem to bring home are empty, I refill them with my own brand of shampoo, conditioner, and shower gel--instead of buying travel-size containers at the drugstore. I toss them, along with other small items (toothbrush, toothpaste, nail file, pillboxes, and a comb), into a medium-size Ziploc bag, and I'm ready to go; the clear plastic lets me find things easily.

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.

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 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.

Avoid spills in your Dopp kit. Cut up plastic grocery bags into little squares and place them under the tops of toiletries to prevent leaks. Discard the squares upon arrival, but bring extras for the trip back.

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.

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!

To find a reasonably priced villa or apartment to rent, try going directly to the owner through a site such as abritel.fr. (Click on the British flag for English.) I arranged to spend two weeks in an apartment in Brittany and one week in an apartment in the Loire Valley, all for a total of $800.

Once we know where we're going, my girlfriends and I divide up the list of things we'd like to do on our trip and put someone in charge of each item on the list. Then that person does the legwork by finding directions and prices, making reservations (if necessary), and researching nearby places to stop for a snack or a meal. Our method means that no one person is doing all the planning.

Recycle the long plastic bags in which you receive your home-delivered newspapers. Slip your shoes into the bags before packing them in your suitcase.

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.

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.

My husband and I keep the stretchy slipper-socks that some airlines provide. (We've gotten them on Virgin Atlantic in economy class and on almost all airlines in business class.) They're great to use when packing shoes: Just slip each shoe into a sock, and you'll prevent clothes from getting marked up by the soles. As a bonus, you'll have slippers to wear when you're away from home. The socks are machine-washable and can last for many years.
