I agree that if I was at a man made lake in the back yard of a Disney resort, I would not be thinking, I bet this water is filled with gators. Just being honest, I would assume the no swimming sign would be because no life guard was on duty, there are boats in the area, or perhaps the water isn't clean enough to swim. While I realize it may not be realistically possible for Disney to keep gators out of every body of water, I'll admit, I would assume there wouldn't be any along the shoreline of one of their resorts.
