You are anywhere near Tennessee and you have a day free, you owe it to yourself to spend at least an afternoon at Dollywood. You can say you don't like Dolly Parton, but everyone loves Dolly. Everyone.
Dollywood isn't your average theme park. It offers local crafts and music, as well as housing the Southern Gospel Museum and Hall of Fame. You really can't go wrong with this place, and it's a great southern treat compared to other parks' overly stereotypical and bland "rebel south" sections. Bring the wife, bring the kids, or just bring yourself.
