Took the family to Dollywood this year and it was by far the best run theme park I've been to. I was amazed at the cleanliness, friendliness of the staff, and how well maintained everything was. The train was really cool too. One of only two times I've been able to see a real coal fired steam engine functioning.
A visit to the Pigeon Forge/Gatlinburg area and the Smoky Mountains is great trip, especially with kids. Lots of quirky nonsense to enjoy, as well as some beautiful nature.
