For the August 13th Allure of the Seas sailing many of the entertainment options are already sold out (comedy live, Blades, Aqua Show). Are these really sold out for the entire cruise or do they still have some reservations that they don't allow you to pre-book? Kinda bummed if we can't see some of these since when we originally looked they weren't available to be booked and then when we went back they were all booked. Thank you for your help!
