This is not personal, but is no one responsible for anything anymore? Do parents have no responsibilty to watch their kids and make sure they are mindful of danger, whatever it may be?In my opinion, lawyers will have a field day with this. You have a beach, that leads into a body of water, at a resort geared towards children. You also have signage that basically admits to the water not being safe. I think you could certainly argue with all those factors it becomes incumbent on Disney to owe a little higher duty of care to their patrons than a sign (that a 2 year old kid can't read, of course) saying to stay out of the water.
I guess people should start suing states for shark attacks because no one protected them. Some things in nature are just dangerous, man. I feel terrible for the family but I just see no way Disney should be held liable for this. It just boggles my mind people can see it that way.
