A Month in New Zealand With No Set Plans

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.

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.

On a trip to Molokai, the plane we were on was small, and luggage was crammed in every which way. At baggage claim, we noticed that someone had packed a bottle of Pine-Sol, and it had broken and leaked everywhere. Now we line our suitcases with garbage bags to protect our clothes—just in case. (It's also smart in case your bag gets left on the tarmac in a downpour.)

At a theme park, tie a brightly colored scarf to the handle of your stroller before you enter a ride. When you return, you'll be able to quickly pick out your stroller from a sea of look-alikes.

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 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.

I carry bilingual takeout menus when traveling to countries like China, Korea, and Vietnam. When I'm at a restaurant with no menu (or one that I can't read), I give mine to the waiter so he can point to dishes they can prepare. I've learned to pack a few extra menus, as the restaurants often like to keep a copy.

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.

If you take an overnight flight to Europe and early check-in at your hotel isn't an option, ask the concierge if you can store your luggage until later in the day and use the hotel gym's shower. You'll be refreshed and ready for sightseeing. Pack toiletries and a change of clothes in your carry-on.

Give your children a coach's whistle in case they get lost; put it on a ribbon so they can wear it around their neck. The piercing sound may be annoying, but you'll definitely find them quicker!

Before you book a room over the phone, peruse the hotel's site for its "Web only" rate. It's often cheaper than the best quote you'll get by calling. Recently, over the phone, I was quoted a daily rate of $129. I booked the same room online for $89.

Flight attendants often work vampire hours and have to sleep during the day. How do we keep the sunlight from leaking into our hotel rooms? We clip a skirt hanger (or two) to the middle of the drapes to seal them together.

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.

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.

Try to book the first flight out in the morning, because those planes often arrive at the airport the evening before. You won't have to rely on an incoming plane, which could be delayed or canceled due to bad weather elsewhere, resulting in your own flight being delayed or canceled.

If you go directly from the air-conditioned ship out onto the open-air deck (which is usually warmer and more humid in most cruise destinations), your camera's lens is likely to fog up. Warm the camera with your cabin's hairdryer on a low setting or briefly leave it out on your balcony so it can acclimate to the weather.

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.

I was heading to the hotel ice machine when I noticed that our ice bucket was looking very tired and missing its disposable plastic liner. My solution: the shower cap that we never use anyway. In fact, it actually worked better than the liner bag because the elastic band held it in place around the top of the bucket.

Easily packable, local specialty foods make great gifts for family and friends at home. At the huge Safeway in Kihei, Maui, we found a great selection of chocolate-covered macadamia nuts and Kona coffee beans in elegant gift boxes for far cheaper than in tourist-oriented shops. European grocery stores abound with gift ideas: British teas, French mustards and vinegars, and Italian olive oils are just a few examples. Just bear in mind that meats, produce, and other fresh items are a customs no-no.

If you plan to leave a gratuity for hotel staff, follow our friend Phil's good advice: Give it at the beginning of your vacation, not at the end. He introduces himself to the housekeepers early in the trip and hands them a nice tip. Guess who always has plenty of coffee and fresh towels?

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.)

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.

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.

When buying bottled water, look at the bottle cap to see if the seal is still intact. While visiting the Acropolis on a very hot day this summer, I caught a young boy refilling empty water bottles from a tap and recapping them. He was then selling the bottles to thirsty tourists.

We always e-mail our itinerary--including flights, hotels, and confirmation numbers--to ourselves and to family members. If our luggage is lost or our wallets are stolen, all of this essential information is just an Internet café and a few quick clicks away.

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.

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.

Get the right maps. For road trips on the Continent, European maps are much more helpful when it comes to reading road signs. They'll say Napoli instead of Naples, Firenze rather than Florence. I could spend all day waiting for a road sign for Munich and miss the exit for Munchen.

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.

My hearing loss once made it impossible to hear any alarm clock. Then I found the Shake Awake, an alarm clock that vibrates. I no longer stare at the ceiling all night prior to an early flight in fear of oversleeping. I clip Shake Awake to my pillow or place it on a hard surface near my bed, where its rattling definitely gets my attention.
