I use my Wyndham points to stay in Pigeon Forge, Tennessee. My Wyndham points trade through RCI.
My home resort with Wyndham is Wyndham Smoky Mountains in Sevierville, Tennessee (Pigeon Forge area). I stayed at my home resort last May and enjoyed my visit. The units have all been refurbished and are nice. The resort is about 10 years old and was built in stages. There are two outdoor swimming pools and two indoor swimming pools. There are two different sections of the resort and they are directly across the road from each other. Here's a link to Wyndham Smoky Mountains:

Wyndham also has a brand new resort in Sevierville that has an indoor and outdoor water park. It's called Wyndham Vacation resorts at Great Smokie Lodge:

I've heard Crown Park is nice to stay at (which is part of Holiday Inn Club Vacations now):

Other RCI resorts that are supposed to be decent are Tree Tops, Gatlinburg Town Square, and Bluegreen's Mountain Loft.
The Gatlinburg/Pigeon Forge area is lovely - the mountains are beautiful. We drove through Cades Cove and really enjoyed the drive back through time.
Good luck with your planning.
