Packing Advice

Regardless of what time of year you travel, good preparation and common sense is a good rule of thumb to follow.

• Planning Your Packing. Anything you forget to pack, you'll have to buy. It is wise to make a list of everything you need to take with you and refer to it as you pack. This will ensure that nothing will be overlooked (and anything that is, is a good excuse to go shopping).
• Preparing Clothes. Lay everything out before you pack. Fold, layer, and pack all like items together. Use undergarments and socks to fill space. Put toiletries and loose items in waterproof containers, in a kit or separate bag.
• Packing For Family Members. With the exception of toddlers and infants, each family member should be able to carry at least one piece of luggage. A small backpack is ideal when traveling with young children.
• Packing For Comfort. Products that will help you withstand the humidity, as well as, sunscreen, are a must. Natural fibers like cotton or silk and light colors are good choices for hot days. To avoid aching feet, pack a pair of familiar walking shoes. Make sure to pack jackets and sweaters for chilly nights.
