Just take care of you and if you have any mobile and headphone then start to listen and any of your favorite song with full volume.
Or start to watching your most favorite movie.Or as soon as possible go to bed and start sleeping deeply
How can I stay in a hotel room with someone I don't like?
Leave the room during the daytime and return late at night.
Avoid seeing or communicating with him or her. But I do not understand why you
have to stay with someone whom you do not like. You simply have to change the
room. I would have left the hotel if I was in your place.
