I'm not sure they have any activities for a child as young as yours appears to be (from the photo in your signature), let alone any where you can leave her. They offer activities, not necessarily childcare. (Except for the kids' night out and even with that, there is a minimum age requirement.)
Why don't you call the resort directly and ask? (843-341-4100) If the resort doesn't offer it, maybe they will know of a drop-off or in-room babysitting service you can try.
