Entertainment?........how about the fact that you're right beside the the most visited Natl Park in the country? Also the only one with no admission fee. We've been going 2 -3 times a year since I was born, and we spend virtually every daylight minute in the park, and I still have only scratched the surface. Ditch all the touristy crap and get in the park. Go explore.
As far as food.......Log Cabin Pancake House, up Airport Rd in Gatlinburg, is dominant for breakfast. Soooooo much better than Pancake Pantry (More overrated than Dan Mullen). As much time as we spend there - almost like a 2nd home - don't really have any really great dinner recommendations...I mean you can get a good meal there, but it's just not a "food destination".
Agree about the park and outdoors. Planning time for Caves Cove, Wears Valley, and wife has never been to Clingmans Dome. Likely one of the horseback tours and have a couple of trail and waterfalls to explore. Only show we want to attend is the Country Opry.
