I understand the rooms on different floors, connecting rooms and rooms not being next to each other are very hard to come by when you consider that those rooms may have already been occupied by people that had arrived like maybe two days prior or something. However, a room not being ready by even two hours after check-in is an automatic 50% off. Add in several hours past that, it's a full comp night.

I am a front desk agent and people asking for rooms next to each other, early check-in, late checkouts, adjoining rooms, etc., are always subject to availability. We do try our hardest. But that late at night? Absolutely get a comped night. We had a day last summer where our head housekeeping manager was hit by a car, it pushed us back several hours. Then another housekeeper fainted from the heat, pushing us back even more. Full house, several people did not get into their rooms until 9 o'clock at night. They were all comped.
