You know, I'm thinking, in addition to the gators, the sand on those beaches can get mighty hot on a warm day. We wouldn't want anyone to burn their feet, so we should probably put a sign up....or on second thought just close the beaches entirely, to be safe.
Probably want to pull all coffee makers out of the room too, since hot coffee can lead to scalding burns, as scientists have just informed me.
Better shut off all hot water sources to the rooms too, just to be safe.
While we're at it, shut off all water so no one drowns in the tub. Can't be too careful.
You realized they have made changes because of hot water accidents. Water temperature is regulated. Hotels used to have the instant hot taps. Despite the warnings right on the tap, too many accidents occurred and so they were removed.
That's not to say Disney - or any property owner - needs to eliminate every danger. But after they have notice of an issue (even one that might have previously seemed remote like this) changes should be evaluated and considered. Cost and feasibility of the changes should be weighed against the danger and likelihood of an issue.
