Described in the roleplaying adventure Night Floors, The Night Floors are a supernormal and nearly infinite array of rooms appended to the Macallistar Building and connected somehow to Carcosa, a sort of interface between the two worlds. They are only accessible at night. As with the Broadalbin Hotel, there is a direct connection to The Whisper Labyrinth from the Night Floors. At least one inhabitant of these floors, Mark Roark refers to them as 'The Hotel', which may imply that they have absorbed the Broadalbin Hotel, as well.
