The pool is heated and there is a hot tub - lots of people in there in March (also, lots of people in there in January but I wasn't one of them!) March can still be pretty cold but you will be able to walk on the beach, ride bikes, fish, etc. There are movie theaters, lots of restaurants, indoor activities run by the cast members, and a game room with fireplace in the "lodge". Also, as mentioned above, Savannah and Charleston are possible day trips.
