I was just checking my plans for my Marvel Day at Sea cruise coming up on The Disney Magic. There are now options to book ticketed character encounters. First one is "Heroic Encounter: Groot" and the second one is "Heroic Encounter: Iron man and Black Panther". It says that I can begin scheduling these encounters on January 29, 2022. This is available on the day at sea as well as the day we visit Castaway Cay.
