*Show of the Month - Suite Life on Deck!*

Zack and Cody Martin (Dylan and Cole Sprouse) are identical twins living in the luxury passenger cruise liner, The S.S. Tipton. The Martin twins attend classes at Seven Seas High, which is a S.S. Tipton school program.

Zack Martin (Dylan Sprouse) is typically the non-studious, outgoing, untidy, and immature twin. He works in the juice bar on the ship as a result of using up both Cody's and his money for the semester. Cody was forced to obtain the job as a towel boy. Zack does not perform particularly well academically, but he manages to perform well physically and enjoys physical sports, especially basketball. Zack acts selfish at times, but he also sincerely cares about his brother, even if he does not always show it.

Cody Martin (Cole Sprouse) is the erudite, mature, intelligent, wise, tidy, and sensitive twin. Cody performs well academically, he is a straight A+ student, and has shown to have a great interest in academics. Cody does not perform well in sports. Cody has been noted to be ten minutes younger than Zack and also often plays along with Zack's crazy schemes. Cody is usually picked on by Zack, but Zack becomes very defensive when other people pick on Cody.

In "Parrot Island," Zack and Cody both had crushes on and fought over the love of Bailey Pickett, a new student at the Seven Seas High School. But in the end, when they found out more about Bailey's life and her ex-boyfriend, Zack loses interest in Bailey and lets Cody have her. Cody attempts several times to attract Bailey, but the attempts were unsuccessful as Bailey seemed oblivious to his advances. Cody's attempts to attract Bailey were finally successful in "Double-Crossed," when Hannah Montana (remembering him from a previous encounter) gave him tickets and backstage passes to her concert in Hawaii. Bailey declared that the concert would be the best date ever, and Cody (after being kissed by her) triumphantly declared that his six-month plan finally worked.

[edit] London Tipton

London Tipton (Brenda Song) is the socialite of the four main teen characters (Zack, Cody, Bailey, and London). She is the daughter of Wilfred Tipton, a multi-billionaire who is the owner of the Tipton Hotel chains, including the Boston Tipton Hotel and the S.S. Tipton. She is described as a "dim-witted, spoiled, gullible, and an often air-headed teenager." When she is happy, she usually claps her hands repeatedly jumps up and down, while saying her catchphrase, "Yay me!" Mr. Moseby fools London into thinking that she is on the S.S. Tipton for a vacation, to get her on the ship. London gets enrolled at the Seven Seas High school program because her father wants her to live in the real world. London does not live in a first class suite at the S.S. Tipton, she resides in a small cabin. London reluctantly agreed to accept Bailey Pickett (Debby Ryan) as her new roommate, although she did so after unsuccessfully trying to bribe Bailey into leaving as she did with her previous roommate. The two later become good friends. In the beginning of the Suite Life series, when London resided at the Boston Tipton Hotel, it seemed she was living in her own bubble. On the S.S. Tipton, London has become more aware of the real world and has faced several difficulties. London also has a pet dog named Ivana.

[edit] Bailey Pickett

Bailey Pickett (Debby Ryan) is a teenage girl from the fictional town of Kettlecorn, Kansas. She is seemingly the perfect girl next door and has been described as a "small town, down-to-earth girl." She shares a room with the wealthy socialite London Tipton, in which the two later form a close friendship together and end up becoming best friends. Bailey is a student at Seven Seas High and attends classes with her new friends Zack, Cody, London, and Woody. She came on the ship to leave Kettlecorn, where she lived on a farm, because she hated the fact that the town is so small. She pretends to be a boy in the pilot in order to get a room on the S.S. Tipton because the girls' cabins were filled. Eventually, she moves in with London when people find out she is a girl. London tries to bribe her not to move in, but Bailey refuses. Both Zack and Cody have a crush on her at the beginning of the series, but when they find out more about Bailey's life and her ex-boyfriend, Zack lets Cody have her claiming that she was carrying too much baggage. Cody tries several times throughout the first season to attract Bailey, but is unsuccessful until the crossover episode Wizards on Deck with Hannah Montana in which they start dating.

[edit] Marcus Little

Marcus Little (Doc Shaw) is a former singing sensation, Lil' Little, who comes aboard the S.S. Tipton. After his voice changed, he lost his fame and career. He attends Seven Seas High and shares a room with Zack. Marcus lived in Atlanta, Georgia as mentioned on his sash in "The Beauty and the Fleeced." He first appears in the second season episode Roomies. He has a crush on London, and is shown to be quite gullible, often believing Woody's tall tales. Marcus has as many famous contacts as London does; however, he is sensitive about the loss of his fame because he believes his celebrity friends won't like him, though he was later proven wrong in the episode "Crossing Jordin."

[edit] Mr. Moseby

Marion Moseby (Phill Lewis), the uptight and serious former manager of the Tipton Hotel in The Suite Life of Zack and Cody, is now the chaperon and manager of the S.S. Tipton. He speaks with a wide vocabulary and an urbane vernacular, and is often annoyed by Zack and Cody's schemes. His repeated catch phrase, "Good luck with that," has become his trademark. He loves bad jokes. Though he acts as though he does not care about the boys, he actually has a great deal of affection for them. He's constantly running from stem to stern keeping the Martin twins and London out of trouble. Moseby is a father figure in London's life, because of London's father absence in the series he looks after her. Moseby reportedly tricked London in order for her to be enrolled in the Seven Seas High school program. He told London she was going on a vacation at the S.S. Tipton to get her on the ship.
