No, it doesn't.
And the number of guests?
Depends on how you look at it. The hotel is always "full" in that all
rooms are occupied; yet it can always accomodate more guests (but not
uncountably many). There are "exactly" as many rooms as guests at any
point, so far as that makes sense for infinities.
That means not fixed infinity. The alternative is potential infinity.
 
Real fools like really counterintuitive "results".
The whole point of Hilbert's Hotel is illustrating the counterintuitivity
of infinite cardinalities.
It illustrates the confusion between potential and actual infinity.
"so daß jedes Element der Menge an einer bestimmten Stelle dieser Reihe steht" [E. Zermelo: "Georg Cantor – Gesammelte Abhandlungen mathematischen und philosophischen Inhalts", Springer, Berlin (1932) S. 152]
If a new element enters, then the old order must be given up. A new number is required.
