One person comes to check in the room and then ten people enter through a side/back entrance which you can't see (please don't start with the fantasy that hotels have tons of cameras because most don't and if they do a lot of times it's for show - meaning they don't record) and then the problem restarts when they check in with a different person who has no clue about what transpired a few months prior.
