I just came back from the BWI and I can tell you there's no reason to concern yourself. It would have to be a very determined, hungry SUPER-GATOR to make it's way into the grounds for feeding.
Now being a resident, I can say that it's common sense to assume any open body of water can have a gator. Especially down here in PBC. Having small children, we simply don't risk exposing them to a potential disaster unless we have some major control over the situtation. Even then we don't take chances.
As for Disney, they probably do have several resident gators, but I imagine the only way they remain in the area is that they are too small to warrant immediate capture.
Even so, while we stayed at the Polynesian and let the kids run on the beach, I was the buffer between them and the water. We didn't let them approach water's edge after dusk. Little things like that.
Personally, I thought it was insane to protect these things and even worse to encourage them to grow in numbers. They've expanded beyond their habitat and are now common in residential areas. Something we've gotten used to.
At any rate, you don't have much to worry about at Disney. If you do become anxious and it begins to make you nervous about your vacation, go make yourself feel better and go slap an environmentalist upside the head. It will be a favor for all of us!
