OUt of context, it's quite simplistic to say that it is cheating. In a situation where people were forced to stay in the same room and SLEPT in the same bed is not cheating. Cheating is being involved either emotionally or sexually or both with a woman and staying in a hotel room in that case is not the definition of cheating. its the emotional or sexual involvement which wouldn't even require a hotel room to carry out.

Being in the same bed with a woman is indeed, not cheating. In and of itself it's an act of resting. But without all of the other qualifications of cheating being given about the show or movie, it's not automatically cheating to me.
