Three of the Disney Channel's most popular shows converge on the deck of one seriously cool ocean liner in this feature-length adventure that will keep the while family in stitches. Justin has just won a cruise to Hawaii. He's bringing his best friend Max along for the trip, and together the pair hopes to get some face time with pretty heiress London while cruising the high seas. Meanwhile, Cody makes a bid to score some hot concert tickets for Bailey, sneaky Alex brings Harper aboard as a stowaway, and Justin is turned blue thanks to a colorful practical joke. Could Zack be the culprit? Later, the passengers go wild when they learn that Hannah Montana herself will be joining them on the cruise. She's positively elated at the prospect of attending the hottest concert on the islands, though her alter ego's excitement turns to anxiety when Miley Stewart's lucky anklet goes missing and her Hannah wig is nowhere to be found. Now, in order to retain her status as the reigning queen of pop, Hannah must turn the ship upside down and mind her missing items before the boat docks in Hawaii.
