Go to the hotel room next door

Well, maybe they have some beer in the room next door.. You put on your shorts and the bathing-wrap that you found in the bathroom and step out of your hotel room. On the corridor, you walk to the next door. You knock; but instead of an answer, you hear strange groaning noises coming out of the room. Well, at least there must be someone in there. You knock again; this time, among the groans, you hear something that definitely sounds like "yeah". Now you´re not just thirsty, but also curious, so you slowly open the door and peek inside.
