Mookie that's great. How old are your children? Ours will be DD6, DS4 and DS2 if we decide to drive down next April. What kind of things did you do too keep them from going crazy?
The only part that worries me about driving down is it cuts into my Disney time

But otherwise not worrying about getting on a plane... priceless.
Our kids are just about the same age as yours....dd6, ds3, and ds2! Here's some things we did...
If you have a minivan with captains chairs in the middle row, take one of the seats out. Put your littlest in the other chair and the two oldest in the back. This does two things....gives you easy access to all kids when you have to climb back there, and allows the 6 year old to help out with the middle child. Also, we had lots of stuff in the car....I had a big bin of snacks, a mini rolling cooler for water and drinks, and another bin for all of their "new toys."
We also had a dvd player. The kids actually were a bit restless on the way down, and didn't use it as much as I thought they would, but on the way home, that's all they did was watch movies. Our 6yo also had a DS that she played. We figured out about 3 days before the trip that with the 2 kids in the back, that might cause a fight, because our middle ds likes playing with her DS too. Much to my dh protest, I found a nice older model used ds at Gamestop for about 45 bucks. I didn't buy him any new games, he had to use hers. But after the trip, DH agreed it was the best money ever spent!
The activities I got them were mostly from the dollar store. There is also a link on the DIS that has printable activities for the road. One was a road trip scavenger hunt (find a green car, helicopter, cow, stop sign, etc.) I printed these out for everyone, and laminated them at home, then brought some dry erase markers with so each one could mark off what they saw. It worked great! Also, there is a page on that same thread to print out all of the license plates pictures for the license plate game. This was A LOT of fun and helped our 2 oldest to better "see" what the plates looked like.
I bought a few used DVD's for the trip, so it was stuff they havent seen. Also, lots of coloring books...no crayons...they melt. Use colored pencils. Best thing we did (which was suggested on the DIS) was to bring a small ball with and stop at rest stops to give the kids a chance to stretch their legs. This was INVALUABLE!!! We brought a small soccer ball, and whenever we stopped, we got out the ball. Just those 15-20 minutes of kicking the soccer ball around did wonders for their stamina in the car...I HIGHLY recommend it!
If I think of any others, I'll let you know, but really, I think the road trip went much better than I had planned....and trust me...if my 3 crazy kids can do it, I think anyone can!
