Plot Synopsis

Zack and Cody Martin and London Tipton checked out of their Boston hotel to embark on a new adventure -- a semester-at-sea aboard a luxurious cruise liner, the SS Tipton, with friend and classmate Bailey Pickett from Kettlecorn, Kansas, and newcomer Marcus Little. In their midst are vacationers and students of Seven Seas High, the one school that London's dad thinks will make his spoiled daughter a better student. While out to sea, Zack and Cody take excursions to exciting locales including Greece, India, Italy and "Licthenstamp" and travel through the Bermuda Triangle. Meanwhile, hotel heiress London is living a "fabu-less" life when she realizes she's actually not on vacation aboard her daddy's ship, and instead must go to school and share a small stateroom. Her roommate, Bailey Pickett, is a sweet southern girl from Kettlecorn, Kansas, who's looking to expand her horizons... but with her new friends, she winds up with more than she bargained for. Marcus Little, a former singing sensation whose career ended when his voice changed, is now making a fresh start by studying at Seven Seas High and rooming with Zack. More often than not, their antics make cruise director Mr. Moseby, who is expected to batten down the hatches as he navigates the growing pains and antics of Zack, Cody, London, Bailey and Marcus. Whether it's teaching the boys a lesson for wasting their allowance or keeping them out of trouble on the ship's Skydeck where the tourists lounge, he's in for a long bumpy ride.
