Also your analogy with rooms doesn't work because infinity is not a number, it is a concept. You could theoretically have an infinite number of rooms, and an infinite number of people, but you then can't just add one person, because an 'infinite number' is not something you can add or subtract to or from."
Totally wrong.
Move all(infinitive) people one room (so people in first go to 2nd and 2nd to 3rd and so on, (infinitive). And 1fst room gets free.
There you go...
This is possible as there are infinitive rooms.

U can actually. I dunno if u know what domain is of a function, but it is a quite possible. Theoretical.
But lets say u cant, then u cant say 0.9999 is 1, as the above is not true. So it cant be said anyway.
Edit:
0.9999(infinitive) * 3 is not 3
