What Happens in Vegas - S1.E4

This week brings another birthday bash, but this one is for Playmate Carmella DeCesare. And it's in Vegas, baby! After waking up at 4:30 a.m. for the trip, the girls (sans Hef) help Sin City live up to its name. They stay at the exclusive Hugh Hefner Suite at the Palms Hotel, flash a window washer, enjoy some cake and cocktails, hang at the pool and engage in a bit of wet 'n' wild group frolicking in the suite's custom shower. But before they know it, the girls' 9 p.m. curfew rolls around, and it's time to get back to the Mansion--even though Kendra's having a wee bit too much fun. The girls eventually get home (a little late) and unwind--each in their own way--which is something they all need after a lengthy, action-packed day.
