I've been trying to figure out something I could put together, kind of like an activity book, but Disney style of course. It's going to be a really long drive for us- roughly 14 hrs. (coming from WV). I was looking at some of the other ideas on the boards, but I think they may be a bit too childish (ie- the coloring books, etc) So does anyone have any ideas for activities to get them in a Disney mood and keep them from arguing for a 14 hour drive?? Maybe some Disney trivia and I thought about rewarding them with Disney giftcards, etc when we get there. Just some thoughts...

Also, maybe some word puzzles or sudoko, or maybe you can make a Disney Trivial Pursuit type game.
The girls actually still loved coloring! The iPod is SUCH a wonderful invention! We had a dvd player, snacks, etc. And whoever suggested having them sleep is a genius. Maybe I should give them Nyquil during our next trip in July... 
And the 20 Questions ball- we have one and may I just say how creepy that thing is! I don't like that it can always guess what I'm thinking of... But I really like the idea of doing some Disney trivia- might have to look in to getting Disney Trivial Pursuit (that does exist right?? what am I thinking... Disney makes everything). Thanks everyone for the ideas. Keep em coming if you have more! And if I come up with anything, I'll post em
When we were tweens/early teens our goal was to sleep as much of that ride as possible. We would stay up together all night before we left, then sleep until we just couldn't sleep anymore! Then we would play games, listen to music, read and just entertain ourselves with making funny faces at passing cars, etc.
