On our drive from CT to WDW last spring, we dressed the kids for bed in sweatpants and then quietly put them into the car at 3 a.m. to leave for the roadtrip. The kids slept for a lot of the drive and we made it through NYC with no traffic.
We bought the portable dvd for the trip, but it didn't get watched as much as I thought it would. The biggest hit for entertainment with the kids was a little coloring kit that I made up. Each kit was in a clipboard with storage space in the bottom for crayons and paper. I loaded the clipboard with plain paper, a set of 8 crayons, stickers, and color pages printed off the http://www.disneyworld.com site. The kids colored for hours! The clipboards cost about $6 at Walmart.

But they knew not to put it in their mouth so if you have one that still does that then be careful.
