I confess, I probably don't get it. But be it, a CG, hotel, or whatever. If you do not like the check out time, BUY ANOTHER NIGHT. Then you can leave when you see fit. How hard is that?
We have done this more than once, and always felt is was money well spent
But to just think of yourself, not the next party that wants your room or CG site, or the people that have to clean the room or site, in my opinion is a very self centered point of view.
And on the other hand " we could not possibly afford to pay for another night" as some would say. Then in my opinion it is, what it is. Don't *****, Buy your own campsite, then you can stay as long as you want
People are so darn cheap sometime, it leaves me scratching my head.
For what a CG costs per night, miles of beaches, trails and on and on, what a deal, almost free in my opinion
