I suppose you are asking about having a sexual encounter with a stranger. It seems to me it is up to the hotel to allow strangers in the rooms or not. It could also depend on the local laws.
Once my Father was staying at a hotel, I tried to visit him, but the hotel forbid me to go to his room! They said that only registered guests could go to the hotel, even if I could show an ID which stated that he really was my Father.
