any tips for driving to disney world with a 2 1/2 yr old boy and 9 yr old girl. . .we plan on leaving in the evening and driving at night so, at least part of the trip they will be sleeping (and our son takes a 3-4 hour nap). any ideas for car toys. we have a dvd player. and got lap tables for the kids. was thinking about colorforms (i think they will stick to the windows of the car for added fun!) anybody have tips? are we crazy. . .
