Quick TR from my first visit to the park:
A friend and I made the drive up from DC to visit Great Adventure for the first time this Friday! It was overcast and in the 50s for most of the day, and some light rain in the early afternoon seemed to keep most of the crowds away. There were no lines for most of the day except from 1-4pm, but after the rain the park pretty much emptied out. The park was definitely understaffed, with all of the coasters operating with 3-4 ride ops - even then, Superman didn't open until around 5pm and the park never opened Bizarro due to staffing (per some of the park staff we talked to throughout the day). Definitely a bummer that we missed the Bizarro credit, but we had a great time otherwise!
El Toro absolutely blew my mind - I was really concerned that there was no way it could possibly live up to the hype, but it was running well and I was surprised how smooth it was. The ejector airtime was insane on a cold April day, and I cannot imagine how insane it is at the end of a hot summer day.
Overall, we had a great time and got super lucky to get a nearly empty park. Thanks to everyone who gave us advice on when to visit, and we'll be back this fall to ride Jersey Devil Coaster!
