Episode 21— Let Us Entertain You

Zack and Cody arrange for their mother, Carey, to vacation on the S.S. Tipton in a luxury suite, but only if she agrees to be the ship's singer, a fact she discovers after the trip has begun. When she refuses to perform, she is forced to move to a cramped, low-cost storage room, but eventually agrees to sing until a sunburn forces her out, allowing Zack and Cody to step in and perform successfully. Meanwhile, London hosts a 24-hour telethon at the Boston Tipton to raise money for the homeless and hungry, but a blizzard disrupts the event, forcing her and others to improvise. After realizing the broadcast failed due to a lost internet connection, they instead donate leftover food to a shelter.
