I absolutely love Minion Mayhem, they hit this one out of the park in terms of bringing new life to an attraction. The whole experience is great. I think the wait time can be a little deceiving depending on how you view it. It seems they're including the two pre-show rooms in the wait time. Personally, the only wait I think about time-wise is the switchback area outside the building, and when it says 75, you're actually only spending about 45 outside, maybe 50, I believe. The actual wait time when I've gotten in line at 75 was probably closer to an hour including the two pre-show rooms.
