MDAS cruises are 5 nights or longer. You will have the 3 regular stage shows. On MDAS day there may be several options in the Walt Disney theatre like a Marvel movie or an evening presentation of the Dr. Strange show. The Dr. Strange show will also be offered during the day on MDAS day. I do not know if they will change things with the shift to the Dream, but on the Magic there was a Mickey and friends Marvel deck show between the dinner seatings and then the big Marvel show on deck after second dining. Hopefully they will keep the deck show, because it is amazing!
