Not to beat a dead horse, but I don't understand why Disney has beach chairs and lounge chairs strewn all over the "sandy" beaches of the resorts. Any parent will know that if you grab some sun in a lounge chair on a sandy beach, your children are bound to head for the water. Wall it off, create a break wall, etc. Just dont make it an inviting place for people to hang out if you dont want them in the lake.
