But why would you want to skip the shows? They are close to the best things about disney cruises. You can spend the day time in the pools when its warmer. On a b2b you get 3 shows. On two ships, for roughly the same price as a b2b you get six shows.
Plus you can skip shows when on two different ships anyway. You arent forced to go to shows you havent seen if you want pool time at night. You simply get more choice about which shows to see.
