Always a challenge to find them, but if you have the book you won't beleive where they have hidden them. And better yet you won't miss any. This does take extra time all the hunting so plan accordingly. Some of the rides may have to be ridden several times to see all the Mickey's. We tried this at Magic Kingdom on Snow White, very well hidden Mickey's in there and it's dark..Look fast while on some of the rides, you may miss the ears..
