The ships are the first in the industry to be designed and built from the keel up as family cruise liners, with the goal of accommodating and equally satisfying adults and children. Unlike most ships of their type, they do not include casinos. Disney ships also feature ship's horns, affectionately known as the "Mickey horn", which play the opening seven-note theme of "When You Wish Upon a Star" from Disney's "Pinocchio", in addition to the traditional horn. The "Disney Dream" and "Disney Fantasy" include other tunes on their horn not heard on the "Disney Magic" and the "Disney Wonder", such as "Do You Want to Build a Snowman?", "It's a Small World", and an elongated version of "When You Wish Upon a Star".
