Sorry...this post must have slipped through the cracks.
I'm not sure what's going on for July 4th this year. Universal had been cutting out fireworks due to the risk of fire during the HP World construction so I'm not sure if anything has changed. If you're going to be over there that day, I would suggest going to the roof of the garage and watching the fireworks that would be presented by the City of Orlando...those fireworks are always beautiful and the parking garage is a great place to view them!
