Cruise Carnival Cruise Lines inks deal to use Dr. Seuss characters By Tom Stieghorst / December 11, 2013 Share 1 -- Carnival Cruise Lines said it will introduce Dr. Seuss characters on its ships in a new partnership with Dr. Seuss Enterprises. A Carnival Seuss at Sea program will include a Green Eggs and Ham Breakfast in the main dining room with the Cat in the Hat and his friends. Dr. Seuss characters such as the Cat in the Hat, Thing One and Thing Two, and Sam will join guests at their tables for fun interactions and photos. Carnival ships will be stocked with Seuss books, toys and themed activities and Seuss movies will play on the line's Dive-In Movies big screen. There will be a Seuss-a-palooza Character Parade and Carnival will build Dr. Seuss Bookville, a unique and dedicated Seuss-themed play space on ships beginning with the Carnival Freedom, which is undergoing a major refurbishment in May, and Carnival Vista, its 25th ship due in 2016.
