We were there last year. However, we did not go to the park on the 4th. We went on the 3rd instead, since they showed the 4th of July fireworks also on the 3rd. The firework show was, in my opinion, beautiful. Worth seeing. We thought about going to the Poly beach to watch the display, however, reading some things on these boards, I got the impression that since it was such a busy time of the year, they really cracked down about turning people away from the Poly if you were not a resort guest. So, you might want to check into that more if you are thinking of watching them at the Poly.
