I have been there three times for July 4th. Don't know about this year, but in the past they had GREAT fireworks set off simultaneously at US, IOA, and City Walk. They also used to have some sort of ticket you could buy for food and a reserved spot at City Walk. We watched the first year from behind Jurasic Park and other times from US. There are HUGE crowds. City Walk is wall to wall people for the fireworks.
