When Should You Consider King Size Beds? There is nothing quite like staying in a luxurious hotel suite with king size beds.

*Oak Hill Inn* is a four bedroom Smoky Mountain vacation home with two full bathrooms and two half bathrooms on almost two acres in the Walden’s Creek area. With a nod to the past, Oak Hill Inn boasts beautiful wood and custom tile floors, custom wall coverings and a winding staircase that leads to the second and third stories. The home can sleep twelve with two king size beds, two queen size beds and two queen size futon beds.
