If you're OK with state parks, Huntington Beach State Park in Pawleys Island SC (South of Myrtle Beach) is a great park. Close to great sea food, less congestion than MB, across the road from Brookgreen Gardens, yet still close enough to MB for all the glitz, shopping, and entertainment. HBSP has full hookups at select sites, a great beach, and a nice marsh boardwalk. They used to allow you to crab there but too many people messed with the aligators.
