A spin-off of the hit Emmy-nominated "The Suite Life of Zack & Cody," the new series follows teenage twins Zack and Cody Martin, and spoiled hotel heiress London Tipton, go aboard a luxury passenger cruise liner, the SS Tipton, owned by London's father, as it cruises the world with tourists and students who attend classes at its Seven Seas High. To his delight, the dutiful Mr. Moseby is reassigned from the Tipton Hotel to be the cruise ship's hotel manager, but is quickly deflated when he finds out that Zack, Cody and London are onboard too. Joining in the hijinks is London's new roommate Bailey, a sweet, southern girl who has just left her small town roots to experience a whole new world.
