All the couples are back for a vacation in viva Las Vegas. Where the old saying goes, "What happens in Vegas...stays in Vegas." One of the lucky couples from the last film is getting married, so each of them split off into gender groups. Each gender determined to have the time of their lives before the big wedding. However, things go haywire, as this may turn out to be one vacation they may not soon forget.

The real standout in this movie was Kevin Hart, playing the loud mouthed confirmed bachelor Bernie, who gets some of the best lines of the movie. He makes the volatile relationship between him and Joan funny rather than sad, when it could have gone either way. Regina Hall had her own great moments, and was no pushover to Hart’s aggressive character.
