Explore Outdoor Australia in a Day (or Two)

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.

For overnight flights, pack a few Oral B Brush-Ups in your carry-on. Before the plane lands, you can "brush" your teeth, leaving you refreshed and ready for the day!

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

Love researching your destination online, but don't know how to organize all those printouts, maps, guidebooks, and tips? I get a 5 x 7" spiral notebook (Mead makes one with a sturdy cover and a pocket insert), a set of index tabs, and some glue. Divide the notebook into sections with the tabs (sights, maps, currency converter, restaurants, etc.). Photocopy—in reduction mode—all the info you want to bring, and glue it into the appropriate section. I leave plenty of pages for my journals. This creates an all-in-one personal guide that you can read again years after your trip!

My husband and I create personal cards (like business cards) before we leave home. We put our name, address, phone, and email address on them, as well as a picture of us. How many people have gotten home from a trip, looked at a slip of paper with a name and address, and wondered, Who is this? The picture helps link a name to a face.

I don't go anywhere without individual packets of antibacterial wipes. I slip some in my carry-on, daypack, and shirt pocket. They're very convenient when you can't find any running water with which to wash your hands. And because they're antibacterial, they're also great for cleaning cuts, and the alcohol from the wipes helps stop the itching when you rub them on insect bites.

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!

In order to keep track of my bags, I use a small metal bell--the kind dancers from India wear on their ankles. I thread it with fishing line and tie it to my carry-on. If anyone touches my bag after I set it down, the bell chimes. It's not a very obtrusive sound, but it's distinctive enough for me to notice if a thief is trying to get into my things. The same bell can be hung on the doorknob inside your hotel room.

Bring your own linens. They're useful in a million different ways. Obviously a soft cotton pillowcase makes those scratchy airplane pillows bearable, but it can also be used to gather loose items when deplaning. A nice sheet will cover up an ugly bedspread or sofa, and makes a great tablecloth or picnic blanket.

I started saving the heavy-duty plastic wrappers that sheets and curtains come in. Most have zippers or snaps, great to hold everything from toiletries to shoes to wet swimsuits. And I bet airport security must love them because they're see-through.

Before you buy expensive bottled water from your hotel room minibar, head to the fitness center. You'll be able to fill up an empty bottle at the gym's water cooler or fountain for free, and you don't need to break a sweat.

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.

We like to buy shipboard souvenirs, so we try to choose a ship that's completing its run of an area--that's when merchandise is generally put on sale. Last year, for example, on a sailing in South America, all of the T-shirts, glassware, and rain jackets were 75 percent off.

My daughter and I bought disposable digital camcorders at a CVS pharmacy before going to Europe. It was a nice way to document our trip--each camera stored about 20 minutes of video. Once home, we dropped the cameras off at the pharmacy. The next day, our DVD was ready. We were very pleased with the quality and the cost: $30 for the camera and $13 for each DVD.

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.

Carry a Polaroid camera when traveling to developing countries. In Cambodia, several village children gathered around us, posed enthusiastically for pictures, and were fascinated by their images in our digital camera. We wanted to send them the pictures, but they were unable to tell us their address. Polaroids would have solved the problem!

Before I embark on a trip, I cover the dirt of my potted plants with plastic bags after watering them well. (Cut a few slits in the bags and keep plants out of direct sunlight.) The soil will stay damp for about three weeks.

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.

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.

When my husband and I would stay in a hotel with our two-year-old, a full night's sleep was out of the question. The minute our son opened his eyes (at 2,3,or 4 a.m.), he woke us, thinking it was time to play. We now pack a pop-up tent and set it up in a corner of the hotel room with books, a blanket, and a few small stuffed animals. The tent folds down to a 14-inch circle and weighs about a pound. It works great! My son has his own "room" to sleep in when we vacation, and we all get to sleep through the night!

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!

With two of our last three car rentals, the local branch wanted documentation beyond the standard insurance card issued by our insurance company. In San Juan, we were delayed a half hour while the agent made phone calls to verify that our liability insurance was good in Puerto Rico. In Miami, if we hadn't provided proof that our insurance covered rental cars, we would've been charged a daily collision insurance fee. Fortunately, we knew ahead of time and took a copy of the pertinent section of our policy. Our credit card included car rental insurance, but proof of that coverage was also required.

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.

Create your own postcards by writing on the back of photographs that you've taken and developed while still on your trip.

Bring a single-hole punch and lanyard on your next cruise. Once aboard, you can make a hole in your plastic key card and attach the lanyard, allowing you to carry the key around your neck. This is especially useful when your dress or slacks have no pockets. Just be sure to put the hole where it won't interfere with the card's magnetic strip.

It's easy to lose track of time in a windowless interior cabin. Before going to sleep, tune into the ship's bridge-camera channel for real-time videos of the front (or bow) of the boat. The screen will act like a virtual porthole, and you'll rise and shine with the sunrise.

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.

On a Northwest flight from Wichita to Cleveland, a piece of my luggage was delivered more than a day after I arrived. In the meantime, I had to buy some replacement items. Save your receipts! I turned in the receipts when I checked in for the return flight, and the ticket agent issued me a $50 check.(Northwest allows up to $50 in interim expenses for the first 24 hours, and $25 for each day afterward, with a maximum reimbursement of $150.)

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.

Finding healthy breakfast alternatives at an airport can prove difficult. I always travel with an insulated travel mug. Before leaving home I fill it with a high-protein cereal and then request low-fat milk on the flight.
