Another idea is the Myrtle Beach area of South Carolina staying at Willow Tree RV resort. This is a beautiful 5 star RV resort just a few miles north of Myrtle Beach in Longs, South Carolina. Fully paved pull in sites that are huge. Beautifully maintained campground that is quiet and peaceful away from all the hub-bub of the strip at Myrtle Beach

It is convenient to historic Brookgreen Gardens, Georgetown, S.C. etc. Myrtle Beach has some nice broadway quality Christmas shows at the Alabama Theatre, and Carolina Opry. Also the newly renovated boardwalk at Myrtle Beach is nice for a stroll down the beach.
There is some great seafood to be had in Calabash, NC just back over the state line from Willowtree in North Carolina. Also excellent seafood in Murrell's Inlet, S.C. Also just a short drive away.
