Ha, with this year's school closures, all bets are off....
It's ok because we enjoy the longer breaks throughout the year, but it does make summer planning a bit more difficult.
Plus, band camp (which is not nearly as fun as you're imagining) is TOUGH during the hottest (and most humid) part of the summer. The kids are generally outside early in the morning, then indoors (or at least in a shaded area of the campus) during the hottest part of the day, then back outside after sunset. Of course, sunset isn't until 8 pm or so... but these kids are dedicated and honestly, I don't think they'd have it any other way.
