Comedy with one specific pool scene

So I’m trying to find this movie to show my friend this scene. I can’t remember the background of the movie but I remember the scene was at a hotel pool. I believe the main characters were a male and female, lets say John and Jenny. Jenny tried to seduce this guy they were trying to steal something from but he wasn’t having it. (They needed to get up to this guys room to steal it) So John ended up “seducing” him to get taken up to his room. When he got up there though, he found out the reason the guy wanted John there was so that John would have sex with his wife.
