I'll be going to Disney World from Nashville the third week of June. We're actually going to break the trip up in two days, with the bulk of the driving on the first day down there and then the second day on the way back. We'll have three girls with us, ages 10, 16, and 19. Is there anything along the way that would be fun to see and make the drive a little less boring? I'm new to this part of the country and have never made this drive before.
