Sorry, but that logic is a bit silly. What you're saying is that as long as your room is ready by 11:59pm, they're in compliance? Obviously things happen so it's going to get missed from time to time, but "after 4:00pm" means 4:01pm or later to me.
Just for kicks, here's the official snippet from the public offering statement for BCV. (I'm pretty sure the others are the same on this point.) I suppose the front desk automatically approves the extention when the room isn't ready, so that's how they'd get around that as a definitive requirement, but the rooms are SUPPOSED to be ready at 4:00pm.
