I am just the opposite. I rarely check in before the office is closed. Most of the parks have a late check in kiosk and do like mrebele says and leave a packet out for you, if you call ahead. I try to get parked, shut everything down, get leveled, and connect to utilities as quietly as possible. I don't think I have ever upset anyone, that I know of. I have even stopped and unpligged my backup alarm when i knew I would be a late arrival and have to back in.
