The Disney Wish is the newest and largest ship in the Disney Cruise Line fleet. It has some unique features, such as the AquaMouse water coaster and the Star Wars: Hyperspace Lounge, which may appeal to you and your family. The dining spaces have also been redesigned to incorporate more storytelling elements, which may be a fun experience. However, as you mentioned, some reviews have noted that the layout of the ship can feel cramped and that some areas can be noisy during shows.
