Looks good, just a couple of comments...one be careful about how high end of cameras and equipment you use, Disney does reserve the right to limit what you can bring.
Also, you should specify which fireworks show it is, we have at least 6 different shows throughout the year at
Disneyland, some are very specific like new Year's eve, others are changed out based on the time of the year.
This one is Remember (I am surprised they are still running it right now, it's normally changed to Magical by now), which I think is the best outside the Halloween Party fireworks.
