This is a must watch for those that want to be disappointed about what was possible using a carousel ride system. THIS is truly what a carousel+ is.
The sheer mechanics of how that ride would work boggles my mind. Just how would Disney get the horses on a mini-carousel to break away and move along a path? And of course they'd have to modify seating that you'd normally get on such a ride to prevent people from just jumping off mid-course.
