I was there on Saturday. Massive crowds. There was helicopters all over the place around 9 PM and I have no clue what that was all about. Both me and the person behind me were confused, because I had never seen a helicopter above Disney never the less 3.
Fireworks were AWESOME. Finally got to do Jack Sparrow thing. The wait was 5 minutes after fireworks because the park died down, but during the day it was 30 to 45 minutes. Never got to ride TSM because it was running between 60 and 75 and Fast Passes were gone when I got there. What caused half the issues is from 8:30 to 10:30 PM they had many rides closed for fireworks. While the fireworks were very cool, I see why they don't do this on a regular basis. Between the shows that close early (Indiana Jones, Beauty and the Beast, LMA, Disney Jr) and the rides that had to shut down during fireworks, it caused issues.
