When Cinematic Celebration ran, they had a problem with guests lining up around the lagoon versus in the proper viewing area. Most of them didn't know the show was happening until it started, so they ended up viewing it from the Louies-Richters & Transformers waterfront, not realizing that the show isn't meant to seen from there.
For Cinesational, they improved lighting in the Central Park area to make it easier for people to understand. I'm hoping Epic is a success so Universal is convinced to run the show far more consistently.
