Your children can then call the various carriers to get pricing, scheduling and other pertinent information. Many will include, if requested, complimentary pamphlets, weather information, packing tips, and other details.
Contact the local Chamber of Commerce for the area you will be visiting. Using toll-free directory assistance your children can request, either by phone or in writing, any literature and discounts that they may offer. You can also pay a visit to a local travel agency and pick up brochures about your destination. If this is a fantasy vacation, try not to take up too much of the agent's time. Most travel agents work on a straight commission.
Your children can then begin to create a folder for each location. Depending on the ages of your children, they can either take one location each, or work on each part of the project separately. Or you can all work together to research each possible choice. Draw the state or country you're planning to visit on the folder cover. Inside they can include drawings or download pictures of the featured attractions, as well as anything else of interest. Information can be obtained from your local library, on-line, or through an interactive atlas or encyclopedia. Using a map, obtained at no charge from your travel club, and a highlighter, you can work together highlighting the various possible routes - discussing the advantages and disadvantages of each.
Prior to packing, you might want to research the expected weather for the place you are visiting at that time of year. Suggested sources to help with your predictions include the Farmer's Almanac, National Weather Service, weather history available on microfiche from your local library, or by contacting the Chamber of Commerce for your vacation spot.
