Any Dollywood pro tips?
If you're going on the weekend, the traffic around Sevierville/Pigeon Forge (Dollywood area) is awful. If you have the flexibility to go during the week, it's much more enjoyable.
The Gatlinburg area suffered a horrible wildfire a few months ago. It destroyed a lot of cabins. If you wanted to go there, you'd probably want to make reservations in advance (b/c of the lower availability).
