If you've ever been staying in a hotel and suddenly the hotel manager asks you to move rooms, you might find it pretty damn annoying. If it happens twice you might find it damn near intolerable. Well let me tell you Hilbert's Grand Hotel is a nightmare. I don't know where he gets off calling it "Grand". Comings and goings all night and the number of times I was asked to move rooms, I can't even tell you.
