I've had staff comment on the room that I'm in when they've asked which room we are staying in.

I've had pool staff deal with me differently, as certain rooms offer "upgraded" pool service.

I really prefer when properties don't do this. However, sometimes we need to stay in properties where there is, e.g., too many rooms and not sufficient pool loungers for everyone, and it's nice when the staff take care of this for me based on room category alone.
