> There was zero problem evacuating 5 people from a room meant for 4. We didn't even get hysterical on the internet. And this was at a one hotel convention.
Nevertheless, hotel capacities *are* a safety issue, and that safety issue is due to fire codes among other regulations.
It's not a problem when one room overloads by one person. It *is* a problem when half the rooms overload by one person, or when one room overloads by 10 persons (and, yes, I've stayed in rooms that overloaded by that much -- other than getting a free room out of it, as the person who actually booked the room, it wasn't worth it at all).
It also depends on whether the hotel charges extra per person -- some hotels charge one rate for the first two, than X extra for each additional person. If it is a hotel that does that, then yes it would be stealing because you are quite literally taking services that have a cost without paying for them.
