All good voyages must come to an end, but for Seven Seas High School students Zack, Cody, London, Bailey and Woody, graduation comes sooner than they expect, and with a lot of baggage, in the momentous series finale of “The Suite Life on Deck,” premiering FRIDAY, MAY 6 (8:00-8:40 p.m., ET/PT) on Disney Channel. Immediately following is a special preview of the new comedy series “A.N.T. Farm,” which revolves around Chyna Parks, an 11-year-old musical prodigy who attends high school as part of the prestigious A.N.T. (Advanced Natural Talents) program.
