Just off SOS on 5/7, this was our schedule. No sign of Hairspray on our cruise, BUT don't miss HIRO, iSkate 2.0, 1977:"A Thrilling Adventure on Ice", Flight Dare to Dream and Jeff Tracta Impressionist. The comedians weren't great and I don't remember much about Jamie Allen the magician (sorry to those performers!).
Due to weather conditions Hiro played on Tues, but Wed performance was rescheduled for Day 7. I suggest booking the first show in case the second show gets cancelled and not able to reschedule. Book as soon as you board the ship!
