By "Not much to do there", do you mean at the resort or on the island? The resort has a full list of resort activities for children and families. And if you're going off-season, there's a pool table and checkers table both in Big Murgie's Den off the lobby (they're there all year round, but in season I expect they're always being used). There are free board games available if you ask the front desk, and free DVD rentals from the General Store/Mercantile.
