What I am mentioning is not a B&B with RV sites. However, it is an outstanding place in the heats of the Pigeon Forge, Tennessee area. Go to Hidden Mountain Resort | Smoky Mountain log cabin rentals in Sevierville TN
and read about it. If you are familiar with the area, it is located on Apple Valley road about a mile behind the Miracle Theater and the Titanic attractions. This means one is in the heart of the theater attractions but far enough away to be removed from the noise and traffic. Hidden Mountain rents Cabins and RV sites, all located on the same resort property. While they do not serve meals, there are several family restaurants within a mile of the resort. The cabins also come with a full kitchen.
