We had 11 (6 adults + 5 kids between 6 and 11). I think our kids enjoyed the house as much as anything we did during the trip, including Dollywood!
Plenty of space, 4 floors of living space and 4 of the kids loved the bunk room. Basement theatre was a big hit and has fun decorative touches. Kitchen is open, spacious, and well equipped. Decks offer great views.
Everything straightforward with check-in and check-out. Property managers were proactive about seeing how we were doing and quick to offer tips for hiking options.
Only cons are minor, a little wear and tear around the bathroom fixtures, at least in the upstairs bedrooms. Also, there is a "boardwalk" to the front door that is down a number of steps and the top landing is sloped, so you have to watch your step.
Keep your eyes open for the bears wandering through.
