1. A day trip to the beaches at Pawleys Island. Much nicer than MB.
2. Brook Green Gardens, just south of MB.
3. A day trip to Charleston (where I live), about 2 & 1/2 hour drive. Walk around Meeting Street, Market Street, East Bay Street. Take a horse and buggy tour of the historic district. Walk Battery Park. Have oysters at Pearlz or the Noisy Oyster. Eat dinner at FIG or Husk or SNOB or Peninsula Grill or Hymans.
As far as actually doing stuff in MB, don't have your expectations up too high and just relax and enjoy your vacation.
