Honolulu: Beaches

I always pack several tea lights, a small vial of essential oils, and matches. Tea lights, when placed in a water glass for extra safety, banish stale or unpleasant smells in hotel rooms. The essential oils work wonders when a drop is placed on a warm lightbulb.

Destinationcoupons.com supplies free discount coupons for cities all over the United States and the world. Print them out on your home computer and save on hotels, shows, rental cars, restaurants, and many other activities.

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.

We were told by an airport security official to tape a business card onto the cover of our laptop. Turns out he has an average of six laptop computers left behind each day! There are so many more procedures now--removing shoes, removing coats--that people forget when they send their laptop through in a separate bin. The official added that it's very difficult to return them because most laptops have passwords that keep the owners' personal information hidden.

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.

Before using frequent-flier miles, investigate how much the flight actually costs. For example, it takes at least 25,000 miles per person to travel from Boston to Alaska. The same flight cost us $288. After paying for our tickets, we received enough additional miles to travel for free to Sweden instead of Alaska!

Therm-a-Rest's Compressible Pillow is perfect for the plane. It comes in three sizes, packs smaller and expands bigger than any other pillow, and is machine washable. Whenever I pull mine out of my carry-on, I get jealous stares: People always ask where they can get one. REI sells the pillows for $18 to $25, depending on the size (rei.com).

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.

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.

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.

Read the fine print on your rail pass. You can often use it to save money on other modes of public transportation. With a Scandinavian rail pass, for example, you'll pay less to ride the ferries. In Switzerland, a rail pass can get you free bus rides, as well as complimentary entrance to museums and discounts on funiculars and hotel accommodations.

To ensure the studs of pierced and delicate earrings don't get damaged, I put them in a film canister. An added benefit is that they're less likely to be stolen when left in a suitcase or hotel room, because thieves presume there's nothing inside but film.

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.

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.

Make a master list of jobs to do around the house before you leave (hold the mail, water the plants, take out the garbage). Keep the list on your computer, print it out, then check off each job as it gets done. You'll be able to go without worrying that you forgot to stop the newspaper.

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 plan to travel to a less-developed country, pack an extra suitcase with hand-me-downs of all sizes. Housekeepers and other resort workers make so little money that the clothes are greatly appreciated. On your way home, you can use that empty suitcase for souvenirs.

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.

Before exchanging foreign currency at the airport, find out if there's a departure tax. At the Bangkok airport, we were very upset- as were travelers around us- to find we had to pay a fee before continuing to our gate. Unfortunately, by that point everyone had cashed in their baht, so the options were a conveniently located ATM, a credit card, or an exchange booth with notably poor rates. When we described this incident to friends, they told us of a similar experience when trying to leave the Dominican Republic.

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.)

A small compass is a great travel aid. Aside from the obvious benefits during country drives or hikes, it's extremely helpful in navigating winding city streets and orienting yourself once you exit a subway station.

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.

When booking a rental car online, click on "special offers" or "hot deals" to find the company's current promotional codes. Price your reservation using each code. Also, keep in mind that rates fluctuate according to seasons and slow periods. I managed to save more than $170 on a ten-day rental in Orlando, Fla.,by changing my reservation dates twice and by using different codes.

Using restaurant.com, you can buy gift certificates good at eateries in your destination city, regularly snagging (in my experience) $25 certificates for as little as $5 to $8.The site is awesome, and it works as well for restaurant certificates in your own city and for obtaining gifts for friends.

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 carrying around my small umbrella, I put it in a Ziploc bag. After using it, I can store the umbrella, back inside the Ziploc, in my shoulder bag without getting everything else soaked.

Shout Wipes take up very little space in your purse or backpack and are invaluable for treating stains. While traveling on an airplane, I gave one to a most grateful Italian after he spilled wine on his tie. Our friendship extended through customs, and we're now e-mail pals. Great stuff!

On international flights, I used to fumble through my belongings--often having to retrieve them from the overhead bin--after a flight attendant appeared with customs and immigration forms. (I don't know of many people who have their passport's number and date of issue memorized.) Now I write all that info on the bookmark of whatever I plan to read on the long flight so I don't have to dig out my passport. I can fill out the card quickly--giving me more time to loan my pen to all the people who never seem to carry one.

My husband and I travel to out-of-the-way towns where rural roads can be hard to navigate. We use a handheld GPS (Global Positioning System) to mark the spot where we're staying, the main highway turnoffs, and, most important, the turns to unmarked side roads. When we're back-tracking and arrive again at confusing intersections, we whip out our GPS and immediately know which route to take home.

Use the shoeshine mitt often found in hotel bath- rooms to store your sunglasses. They fit nicely inside the pouch, and when you take them out, you have a soft material to clean them with. For extra protection while traveling, I store my sunglasses inside the shoe-shine mitt, fold the end closed, and then place it in my glasses case.
