    Or you could just walk to room infinity + 1 and not disturb an infinite number of guests, dick.

      You can also just ask the staff to change the room numbers and send everyone an update. That way you get a room, no one is disturbed and people running the hotel have an infinite amount of work to do!

      But it would take an infinite amount of time to get there!

        Is it better to inconvenience one person an infinite amount, or an infinite amount of people a medium amount?

          I feel like my odds of avoiding getting my ass kicked are better inconveniencing just one person.

        The journey of a thousand miles begins with the first step.

        … Well, better get to walking.

          We are not talking about a thousand miles but infinite miles. That’s not the same order of magnitude at all but a factor of infinity

            Well you’re definitely not going to get there if you spend all day explaining infinity to people.

      You can’t actually. If there’s an infinite number of rooms and infinite guests occupying them then there are no open rooms.

        Next-best strategy: make the set of guests who have to be moved arbitrarily sparse, so that 0% of the hotel’s guests need to be bothered. Oh dear, that’s still infinity of them.

          This is a great plan, but it is critical to not be the person to notify each guest. Infinite calls to inconvenience infinite people sounds like hell.

          You mean ~0%. 0 is 0

        Depends on the size of the infinities. If you have an infinite natural number of guests, but infinite real number of rooms, then you have more rooms than guests.

          If you can see doors to enter each room, then they are countable.

            How do you know the uncountable doors aren’t there? You wouldn’t be able to see them amyway

              How would anyone get into one of those free, uncountable rooms if they can’t see them.

        Wrong: ∞±n = ∞

        The concept of infinity is well-defined in mathematics. It goes much deeper than that, with countability and differently-sized infinities, but if there are infinite rooms, you always have space.

          Yes, but walking down the hallway you’ll never find an open room. Space can be made but you can’t just go to the ∞+1 room.
