Zack & Cody On Deck is a Disney Channel original series. It is the sequel to The Luxury Life of Zack & Cody. Zack and Cody are again in this drama. But this time they are in S. S. Tipton, not the Tipton Hotel. There they go to the school called 7 Seas High. They find new friends. There has been a small change in the old cast of the series. Debby Ryan (Bailey Pickett) replaced Ashley Tisdale. Maddie (Ashley Tisdale) goes to college in Boston; that's why he's not on this journey, but he was a guest on the series in the episode "Maddie On Board".
