Thanks for all the great tips, everyone!
We'll be making the long drive from Maine to WDW next week, so I'll be putting a lot of your wonderful ideas to work! My DSIL, who is riding with us, has made up goodie bags for the kids. They get one for each state line we cross. She got a lot of stuff from the Disney Store when they were having a big sale a few weeks back. We also just got a new van with a DVD player, and that will probably be a life saver!
