Was there this weekend. The ride was 90 minutes on Saturday afternoon. Some of the lowest waits I've seen for it since opening. I had FP and it was really smooth. I didn't realize the first time I rode it at opening I waited probably a whole hour even with FP as the line was literally still outside. But we were probably on and off the ride this time in 20 minutes.
It was my second ride and I enjoyed it as I felt a lot less sick. They had a lot of wind blowing so it was nice and cool. I mean I was still sweating but I was fine.
I still need to see the whole queue so I can judge the whole experience but from the parts that I have seen, just one of the best attractions in Orlando. So beautifully executed, even if it's next-gen BTTF/Simpsons.
