You can do "Disney A-Z"...start with the letter "A", and everyone names as many Disney-related things (movies, attractions, characters, etc.) as they can that start with "A"...then you go to "B", and so on.
Or someone names something Disney, then the next person has to name something that begins with the last letter of the previous word, e.g. the first person says "Tinker Bell" and the second person says "Lady and the Tramp", then the third person has to name something starting with "P".
