"Senior Ditch Day" is the twelfth episode of the third season of The Suite Life on Deck and the sixty-first episode overall.
Zack, London and Woody go to a ritzy beach club for Senior Ditch Day, but when the bouncer won’t let Woody in, London and Zack go without him. In an effort to get in, Woody claims himself as royalty and becomes a jerk to London and Zack when they ask to be in a VIP area with him. Meanwhile, in an effort to keep their perfect attendance records, Bailey and Cody show up for class, which annoys Ms. Tutweiller who was looking forward to her day off. She's forced to show them how to have fun, which they think is a class; at wit's end, she says they pass.
