Maggie Valley is tough for name brand RV spots. Go on line to
www.maggievalley.org and click lodgings, then campgrounds for a list. I would call the number provided on the master site and talk to them for a better feel.
Also, whether you are a history or motorcycle person, you NEED to visit the classic museum: Wheels Through Time. Dale has over 250 antique machines all displayed so your interest is ramped up from the moment you walk in the door. It's nationally known and unique ( To say the least ). AND the kicker is, they ALL run. You will NOT be disappointed. We rode our motorcycles from Atlanta 2 years ago. Day we were there about 200 police riders were there , Blue Knights MC Club. Dale has been featured several times on TV and is friends with Mike from American Pickers.
99.5% of museum are motorcycles .
