If a location in central North Carolina is needed I'd suggest Tanglewood Park in Clemmons, NC just off of I-40. It offers a smaller campground with large shaded full hookup sites. Inside the campground is a large covered picnic shelter with AC power that can be reserved.
The campground is adjacent to (and has access to) a large county park that boasts two golf courses; horseback riding; fishing in a large lake or river; large family oriented swimming pool; mountain bike and hiking trails; and a bed and breakfast with a beautiful arboretum.
There is a hospital literally a mile away, and a Harris Teeter grocery store across the street from the entrance. If there were folks that weren't into camping, in addition to the manor house on the property, several hotel locations are available minutes away.
There are several other attractions within a short drive including Ray-Len winery; Old Salem; minor league baseball; the largest mall in the southeast; and Foothills Brewery.
I live just around the corner from here, so I'd be happy to help with logistics if needed. I'm not a paid spokesman....just proud of my community!!
