South of the Border is a really cheesy place to stay about 1 hour over the SC border. They have cheep motels, a strip mall to buy cheep stuff, places to eat, and a gas station. We have stopped there once for the novelty, but never have stayed there.
When we have driven, (7 times) we have done all sorts of things to mark the miles and pass the time. We try to stop every 2.5 hours just to get out and stretch. Then each time we hit a new state, I break out a silly game. We have a car bingo that we do; I made cards with things like road signs, license plates with different states, and things to read the advertisement. Then I give out Disney dollars for the winners. I have also done Disney trivia and have done map quests. I take old Disney maps and then have everyone look for things on the maps like the closest bathroom to the entrance, or the farthest ride from where we are having dinner....again winners get Disney Dollars.
Those things really do help them pass the time. For the ride back we have usually picked up something they can play with in the car from Disney and I save some games and videos too.
Hope this helps.
