I don't believe Fantasmic honors Fast Pass + anymore. Folks with FP+ have had to wait with everyone else and get escorted to the same seats as everyone else. At least that's the way it was last month....
It has FP+. It's just that it's crap.
I was actually really wondering about MSEP. I LOVED the FP+ area this past September... hoping it hasn't changed and that I could get one for the second parade on our next trip.
