It's the job of the hotel to see that the room as booked is the room that is provided at check-in, unless one is getting an upgrade because of elite status or overbooking the cheaper room classes. It's not the job of hotel management or desk clerks to determine who is 'worthy' of the room they have actually booked.

As long as the number of guests is equal or less than the legal occupancy of the room and that number is properly reflected in the room rate, it's none of the hotel's business why a room of a particular configuration is reserved.
