I 3rd, or 4th, or whatever this.
Been countless times in warm weather and twice in January. I have a hard time telling people why the place is so great, but I keep going back.
We've been staying at various hot tub cabins off the main road in Gatlinburg, hang a left at the smaller split in the road on the main drag. Usually 8 people splitting a 4 br cabin makes it dirt cheap, plus there's instant drinking buddies. Tiny, 1br places are cheap now too.
We also went to a cabin at Burr Oak State Park a few years ago. Not bad, but not much to do in the Winter.
