You need not wonder about what to do. Once you're there, you will wonder how to fit everything in. The resort has a wonderful recreation program, with programs for families, adults, teens, and kids. There is some activity available from morning to evening. For example, you can choose from cooking demonstrations, wine tasting, kyacking, dolphin watching, magic shows, campfires, bird watching, beach nature walks, bike riding, etc. And I haven't even mentioned the pool and beach and the activities there. You don't ever have to leave the resort.
There is live music over at Shelter Cove (a five-minute walk across the bridge) several times a week. For a dinner and music treat, The Jazz Corner in Wexford Plaza not only has wonderful food, but wonderful music.
And as already mentioned, Savannah is a stone's throw away and is a fun place to spend a day. The Trolley Tours are informative, and a good way to see a lot of the city in a short time.
Better hurry for those ressies.
