I don't recall BGW every citing a specific capacity. Just them saying that they would like between 6-8,000 people. I know some politicians kept saying 24,000.When they were first lobbying against the initial restrictions, they cited capacity as around 24,000. That’s much lower than the number on Wikipedia, but it’s the number they gave us, so ¯\_(ツ)_/¯.
I do know that CT has the lowest capacity because so many rides are closed and they close the park for guests when they are at around 22,000. There should be room for at least few thousand more in the ride queues. So probably looking at around 26-28,000.
I'll be honest with you though. The park actually doesn't have enough parking spaces to reach it's max capacity at a given time unless every car pools and has a full car.
