I haven't found there's a difference - a punter who's unpleasant, rude or unhygienic isn't any more or less likely to be so because of what the clock says, and if you're screening properly it shouldn't make any difference.
I don't work late when I'm at home, but I'll go up to 10pm or so when I'm in hotels and have never had problems bar the odd drunk numpty who I should have turned away on arrival and didn't (and I've had drunks turn up at all times of the day).
The only thing I will say is that some hotels ask to see keycards after 11pm-midnight ish, so if you're planning on working late I'd recommend checking
