Create a vacation scrapbook as you go.
Everyone likes to reminisce about past trips, but few parents have time to create photo albums and scrapbooks. So enlist the kids to help. One person can be in charge of taking photos, another of recording what you did each day in a journal. A third can collect mementos: souvenirs from various attractions you saw, coasters from restaurants, a feather found on the ground of a wildlife sanctuary.
Pack instant cameras, paper, markers and crayons, glue sticks and tape. Each night before bed, kids can fashion some pages representing the day's activities. Then when you're home, set aside a special family night to look through their special creation [source: Car Junky].
