The motto at Jeff Lewis Design has always been to work hard and play hard, so when Jeff books another speaking engagement in Las Vegas, he decides to throw Sarah a bachelorette party and bring the whole gang along for the ride. It's still a business trip however, and when Gage and Jenni are the only ones to show up for the actual speaking engagement, Jeff realizes that he may not be able to rely on his staff as much as hoped. Meanwhile, back in LA, it's finally time for Zoila's birthday facelift.
