<P> Dave, a dealer for Guitar Hero, and Ronnie, a stay - at - home mom, are a typical couple raising two young children in the suburbs of Chicago . They experience various stresses including redecorating their house and raising their kids . Joey and Lucy are high school sweethearts with a smart but naive teenage daughter named Lacey . Their relationship is on the rocks and they are even considering a divorce once Lacey goes off to college . Jason and Cynthia are a neurotic couple who've experienced multiple failed attempts to conceive, and Shane, recently divorced from his wife, has a much younger twenty - year - old girlfriend, Trudy . </P> <P> At Dave's son's birthday party, Jason and Cynthia, using a PowerPoint presentation, announce their troubled marriage and they are considering divorce because they cannot have a baby . As a last - ditch effort, they have found a couples therapy resort named Eden . A deal called the Pelican Package is half the normal cost if they can get three other couples to join them . In their presentation, they show beautiful pictures of sunlit beaches and beautiful locations . They also assure the others that the couples therapy is purely optional . </P> <P> Dave and Ronnie discuss their inability to go because of childcare responsibilities and decline the trip . In the middle of the night, their home security alarm is activated when Jason shows up unexpectedly to further sell the idea of the retreat . The commotion wakes the kids, who have overheard their parents' conversations of not being able to go because of them . Fearing that their parents are contemplating divorce, the kids have already arranged for Dave's father, Grandpa Jim - Jim to babysit so their parents can go to Eden . </P> <P> The retreat proves to be divided into Eden West and Eden East . West is for couples and uses the tagline "Stay Together". East is for singles and uses the tagline "Come Together". East and West attendees are not allowed to intermingle . </P>
