If this year is like last year's fireworks IOA's Fireworks are a let down. I thought that it would be great to watch a great fireworks display on the IOA lagoon form the Jurrasic Park Discovery Center but was extremely disappointed to see a fireworks display that took place only on the lagoon that me, a couple of buddies and and a couple of hundred bucks spent at the local fireworks stand could easily duplicate. While watching the IOA lame fireworks, we heard Universal's going off in the distance. They actually went airborne and we had seen the majority of them from the Hard Rock Hotel Parking lot the night before and what we saw from outside the park was far better than the IOA attempt.
Based on last year's fireworks, Don't waste your time at IOA or worse yet at Citiwalk trying to view both theme park's fireworks simultaneously, just go to Universal or even the Hard Rock Hotel's Parking lot and enjoy.
HAVE FUN
