The pools I used as a kid and then a student seemed to have much better safety and security than what I have heard of the Villages' sports pools. These were either pools for University students with valid IDs or paid admission pools which were the county and/or city run. They had admission attendants as well as lifeguards.

The Villages family pools actually sound like they have much better security than the sports pools as I would see frequently ID checkers there and the rest rooms there had doors that lock. I did not always see ID checkers at the family pools but at the hottest parts of the day they were usually there.

Volunteers from the Villages' residents might be a fiscally reasonable solution for the Villages' management. They would probably be a deterrent to almost any wrongdoers. Especially if they have phones with picture taking ability if they see a male heading into the female showers or vice versa.
