Not as rarely as one might think. We've been in situations where the hotel is expecting a large number of guests due to a convention or conference starting the next day. We were recently at the LALive Marriott on business and our group occupied the entire hotel. In a case like that, the hotel management puts a lot of pressure on front desk personnel to get existing guests out just as early as possible because housekeeping is going to be unusually busy getting all rooms ready for occupancy. This can be a daunting task.
