What exactly are you looking for? seclusion? Amenities? Gerties is near Asheville and lots to do in the area. Beautiful CG too. Other than that you're looking at Pigeon Forge/Gatlinburg....well, there is Maggie Valley too. All nice campgrounds to be had. All depends on what you want.
Dollywood is all fancy Christmas lights at that time and the restaurant at Dolly's hotel is wonderful for an anniversary meal. It is open to the public. The area has many dinner shows to see too.
In Asheville the Biltmore has its candle light Christmas evenings going on. Very romantic. I'm booked there for a night at their Village Hotel for it.
