It's A Loonngggg Drive....well you know.?

I'm going TO Disney World FROM Slidell, LA. What can I do to entertain myself for the 9-10 hr trip in the car? I have an iPod and cellphone, and a DVD player, but I don't like watching DVD's and I dont want to burnout all of my iPod battery. All I can do is listen to music, text, and watch a DVD. Any other ideas? It's my 7th time going and still have no plan...
