3D---if you liked Fripp, you would love Pawleys. MB is about 20 minutes north, Charleston, 60 minutes South. It is very historical, rustic, and charming. Not a lot to do except shop, eat (no chain resturants just good local seafood cooked by good local cooks, and sit on the beach--which is the prettiest I've ever seen. It is the definition of shabby chic. Most of the houses are modest in terms of beach houses...nothing fancy. The island is small--and unless your cross the causeway to the mainland, there is not a store or resturant in site----of course the mainland is only 1/2 mile away. island sits between a creek and the ocean--and is only two streets wide.
I 10 live 10 minutes south of there in a very old seaport town---we have a charming waterfront with dining and shops. There are tour ships that take you along the waterway where it the ocean meets the river and to the various lighthouses in the area.
