We are leaving in the middle of the night and plan to drive at least as far as Nashville, but hoping to make it to Chatanooga or further. We have a 2 year old and 6 year old so how far we make it largely depends on how they are doing. I was thinking of making a couple reservations and then seeing how things are going during the day. We were planning on not making reservations but that seems to be largely frowned upon on here. Any suggestions on where to stop throughout the day for the kids to run around a bit? It would be great if we could find a hotel that caters to children for the night, maybe with a water slide or something. Any suggestions?
