Yes, but it's been about 4 years ago. It was a charming place. Unlike staying in a hotel there was lots of green space and playground equipment for the kids. The only complaint was that the mattresses felt as old as the wigwams! There were large coils that you could feel. Even though our son was only 5 at the time he complained about how uncomfortable the beds were (and this is a kid that can sleep about anywhere). I would recommend calling and inquiring if they have put in new mattresses before I would stay there again.
There are lots of family friendly acitivities in the area. Ky Down Under takes a couple of hours to go through and has a small cave (takes about 30-45 minutes to go through it). There is also a small amusement park, Ky Action Park. It has a fun Alpine Slide, bumper boats, miniature golf, bumper cars, and offers horse back riding. I haven't been but many friends say that Guntown Mountain is fun too. The funniest thing is Dinosaur World. There are large replicas of many dino's and they are painted bizzarre colors. Of course who could prove that t-rex wasn't purple?
