My friend and I (both adults) rode it last year with FP+. For both of us, our reaction was "it's cute, but it's not something I'm stressing over another FP+ for, and I wouldn't wait more than 20 minutes for it." But I realize we are in the minority.
And just as a disclaimer, we are not "MUST BE THRILL RIDE" people - we like them of all types. This one we just found ok. Maybe we built it up to be too much in our heads?
