Just traveled here with 3 families. We rented a house on the golfcourse that is part of the resort. It was very nice. The resort itself is just typical tourist stuff to get people to spend money. The water park is small as far as the indoor part goes. This January so the outside part was closed. The lines were long (30 min avg) and the slides were just ok. Kids running around with no supervision and wholly cow - there is no weight limit on bikinis! If you have small kids and you want to blow some serious money then go. Otherwise, I'd try something else.

They have some things here our family has never seen before at a resort. The indoor activities are a blast. The temps were warm enough as long as we went into the hot tub last. If I tried to go from hot tub to wave pool, was too cold for me.
The indoor treetop rope maze was really cool, something to remember, however did not care for the arcade below. The card/point system seemed more complicated than necessary and a little buggy.
Room was just perfect, very clean and everything worked as it should. It even had a little built-in stove, which was unexpected.

We ate at the Thirsty Miner, was a little expensive for what we got, but was kind of expected since it was on site and had a nice overview of the waterpark.

We would definitely go back.

We stayed here for a weekend for our youth ministry retreat and our teens loved it. The lines in the water park were long, but of course the hotel was packed. The arcade is very reasonable. The snack prices were equal to a place in a less populated area. (Personal Pan pizza 5.95) There is a ropes course an play ground reaching high above the arcade. The rooms are nice and clean and the beds are comfortable. There are shops comparable to those in Gatlinburg. There is a restaurant with a buffet that I have not tried. There is a pottery painting shop as well.

We had so much fun at Wilderness at the Smokies! We have two girls, ages 10 & 7, that absolutely loved it! There is so much for them to do between the indoor water park, the Adventure Forest and Polka Dots Pottery. We were there for the whole weekend and never even had to leave the premises! We ate there, did activities and had a blast! We will definitely be going back!!!
