Then housekeeping has to re-clean infinite rooms before everyone can resettle, which only works if you have infinite cleaners. Just walk down to the infinite + 1 room and no one has to move ;)
I once brought infinite* baggage to the infinite hotel. I was told to leave an infinite** amount of times, but I have an infinite** amount of time to wait in at the hotel lobby bar, drinking infinite** beers, until the infinite* taxi's arrive.
i’d ask them to label their rooms with ordinal numbers instead of cardinal numbers, and then i’d move into room ∞ + 1 (i.e., ω + 1). everybody else can stay where they are.
