Adding another person to a hotel room
Question
Shalom.
A couple rented a double room in a hotel and were given a room with 3 beds. Are they allowed to bring their child, for whom they did not find other sleeping arrangements, to sleep in their room (on condition that they do not use anything beyond what they would have used without the child)?
Answer
Shalom u’vracha.
No, they must ask permission from the hotel management.

Shulchan Aruch, Choshen Mishpat 363:6: One who lives in his fellow’s courtyard without his knowledge, and it is designated for rental, must pay him rent. And, certainly, ideally he can prevent him from using it even if it is not designated for rental. (However, in our case one must discuss whether this is considered “designated for rental” after they have already been given the room and no one else will be put there.)
And it can be said that in relation to them it is considered designated for rental, since if the couple themselves wishes to bring in another person or family member, they will have to pay additional money and then they will be allowed to bring that person in.
