We had a great time in the Gatlinburg area last year! We stayed at the Buckhorn Inn which I don't recommend. It sounded great, old cabins in the woods with lots of history, but when we pulled the tarp and oil out, the bugs on the floor showed themselves and wigged us out.
If you can't have fun there, you just aren't living!
When we showed up we cruised into Gatlinburg all nice and easy, then BAM! Hard Rock Cafe' and a bazillion people. But that's because we went during Thanksgiving.
Hopefully everything will be open and be sure to hit a go-kart track.
