Like I said in another message, FLORIDA'S newer schools are built as hurricane shelters. Local residents have first choice at staying in one, while travelers have to take their chances. If someone gets stuck somewhere in a motor home because they can't find fuel, chances are that there will be no place to stay.
The school closest to me has had to use theirs several times when the feed to the school was damaged. They can't afford the liability to send them to empty homes. So, they might as well run the generator and keep teaching even if the air conditioning isn't working.
That was 50 years ago, when the buildings were designed for high humidity, and sitting empty all summer. hell, your local news was talking about portable buildings at one Orlando school spending $50,000 a month to air condition them, until they could be moved. If they aren't air conditioned, they will develop black mold. The ceiling tiles will buckle, and the wood trim will warp.
