Get ready for a festive summer as Hallmark's 13th annual Christmas in July event is just around the corner! PEOPLE exclusively revealed that the celebration will kick off with the premiere of "Christmas at Sea," a reality show filmed aboard the Hallmark Christmas Cruise last November.

The four-episode series, which premieres on July 7, features real-life fans living their dreams alongside their favorite Hallmark stars, including Benjamin Ayres, Jonathan Bennett, Wes Brown, Erin Cahill, Paul Campbell, Taylor Cole, Nikki DeLoach, Sarah Drew, Tyler Hynes, Kimberley Sustad, and Andrew Walker.

The show follows the stars as they mingle with fans and participate in festive events like carol-oke, holiday competitions, and even help a couple tie the knot! In an exclusive trailer, Campbell chats with a man in the gym who reveals his plans to propose and then get married throughout the trip.

The show will also feature a teenage grandson celebrating his 16th birthday with both of his grandmothers. Throughout the journey from Miami to Nassau, Bahamas, aboard the Norwegian Gem, the fans and the stars bring joy and hilarity to every event.
