This week the finalists must collaborate to create a fantasy wedding reception that is both fabulous and functional in just 24 hours. The bride and groom will provide their wishes for the theme and color, but the finalists must figure out how to exec... (more)ute the couple's dream design while accommodating practical needs including seating, lighting and space planning. Event planner and former Real Housewives of New Jersey cast member, Dina Manzo, will tour the party set-up with judges Genevieve Gorder and Vern Yip. Meanwhile, mentor David Bromstad will ask each finalist to deliver an on-camera presentation of a party-styling tip that they included in their design.
