Las Vegas, Air/Hotel, From $309

If you're on a road trip with young children and you're looking for a place to let them blow off some steam, check out the playgrounds at local elementary schools. They almost always have equipment that your children will love to explore. It will also give everyone in the family a welcome chance to stretch their legs.

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.

Be certain to have enough blank pages in your passport. Someone I know had a terrible time getting per- mission to board a flight from Zambia to South Africa because she didn't have the two blank passport pages required to enter South Africa. Thank goodness my husband had read about the requirement. Before the trip, we sent our passports to the center in Charleston and had extra pages added at no charge.

Disposable-camera lenses scratch just like any other lens would. Place a small piece of painter's tape (or another kind that won't stick too much) over the lens to protect it from contact with other items in your purse or backpack during travel.

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.

If you wait to buy a discount-granting Entertainment Book until around six months before it expires (expiration is usually scheduled for November), you can often buy a $20 to $47 book for as little as $10, plus $5 shipping. Online access to the coupons is sold for $7 a month. These are great for vacations out of town.

Anyone tired of the same boring postcards that are found at every roadside tourist trap should try shopping for vintage postcards at an antiques shop. They're a great addition to any photo album, as they often show what the local attractions looked like prior to development.

Before you head to the airport, make a list of all the items in your checked luggage that would be prohibited in your carry-on. If an item (such as a knife for a picnic) makes its way into your purse or daypack during your travels, it should be accounted for when repacking and put into the checked piece to avoid hassles at airport security.

A simple but effective anti-pickpocketing measure is to fasten a safety pin across the opening of the pants pocket on the inside. Leave enough room to pull your wallet out with some effort, but not enough for a quick hand to lift it in a second or two.

If you can't sleep due to the heat in your non-air-conditioned hotel room, take a cold bottle of water and place it on your pillow, in the crook of your neck. It will cool your whole body down.

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.

Everyone knows that duct tape is great for helping out in travel emergencies, but no one wants to lug around a bulky roll of the stuff. By wrapping a few feet onto a pencil or ballpoint pen, you'll get a miniature roll that does not take up much in the way of additional space.

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.

In Europe, my husband and I like to use public transportation. As a result, we frequently find ourselves studying itineraries displayed on train station walls, trying to read schedules posted at bus stops, or staring at kiosk-size town maps. On our last trip, my husband snapped digital photographs of those things. We were able to take the map or itinerary with us and could refer to it as needed by using the zoom feature.

Most hotels provide cloth shoe mitts but not polish. In a pinch, a dollop of skin cream on a shoe mitt (or even a tissue) can make scuff marks vanish and leave shoes as shiny as if they'd been cleaned by a pro.

I teach a Tulane University seminar on independent European travel for first-timers. Until recently, I advocated Europe's great rail networks as the way to go. Now, with the plethora of budget airlines, I recommend a combination of the two. But it makes the planning stage—which I find almost as much fun as actually taking the trip—more involved. Thank goodness for whichbudget.com, a Web site that lists, by city, which budget airlines serve which cities. Then, to find links to all of Europe's state railway Web sites, visit railfaneurope.net. Each site generally features a travel planner and, almost invariably, an English-language option.

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!

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.

Though they're often the best deals around, don't assume that packaged vacations always offer the biggest bang for your buck. My wife and I were ready to book an air/hotel package to Maui when we noticed a sale on Aloha Airlines ($280 round trip from Oakland). I added up the total cost of the trip if purchased separately and saved $400 over comparable packages from various tour operators. We used the extra money to stay in a nicer hotel and to rent a convertible!

Instead of bringing one of those bungee cables to hang-dry my delicates and socks, I pack a couple of mini plastic hangers--the ones that bras and panties come on when you buy them. They take up very little room in my luggage and can be thrown away at the end of the trip.

I work for a major airline and can attest to this tip for redirecting lost luggage. Place a copy of your itinerary--including contact info for where you're staying--inside your checked suitcase. If name and flight tags are missing, we'll still know where your bag needs to go.

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.

When overseas, I carry a "cheat sheet" that includes exchange rates and metric conversions. Currency conversions are available at oanda.com.

Spring skiing often means a wild temperature shift from morning to afternoon. If you want the option of removing outer layers or switching to a lighter ski jacket midday, attach the lift ticket to your clothing with a split-ring key ring. You'll be able to move your ticket as the weather warms up.

After looking for years for the perfect toiletries bag and being frustrated by many that were less than ideal, I finally discovered one that is just right: a soft-sided lunch box I bought at the supermarket. It has an outer zipped pocket with small compartments and slots perfect for often-used items like a toothbrush and toothpaste. There's a small removable zipper pouch inside (meant for a small ice pack) for those smaller, hard-to-find items like nail files and pill bottles. The remaining space inside is just right for larger items like shampoo and hand lotion. Other helpful features include both a small handle and shoulder strap and a waterproof, easy-to-clean interior. As an elementary school teacher, I know firsthand that it'll last: It was designed to withstand daily use by kids!

After I fell into a stream in Cambodia, my digital camera wouldn't work. Someone suggested leaving the camera in a bag of rice overnight to draw out any condensation. By the next morning, it was dry and working perfectly.

When we visit places we think we might return to, we collect copies of free tourist magazines. At home, we write the address of each magazine on a postcard. Six to eight weeks before our return visit, we send out the cards asking for a current copy. The magazines are full of useful information.

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!

If the zipper on your luggage or your clothing is giving you any trouble, rubbing some lip balm or candle wax onto the teeth should loosen it.

No longer do the many key chains I get as advertising languish in bureau drawers. I attach one or two at the ends of my luggage zippers. They make it easier to work the zippers and help me identify my luggage on airport carousels.
