The movie magic occurs on the Chinese theater right before the Star Wars fireworks. The best spot in my opinion to get a good view of projections and fireworks is to be at the corner of the taped off section next to the wheelchair and dining party section. It’s right behind the walkway they leave open.
At the beginning of the month, we got our spot at like 6:45 for the fireworks starting at 8:15 and we were the 3rd group sitting to hold seats in that area
