The Abbey Stone Theatre was built to facilitate shows that were standard scale for Broadway at the time. Secrets of Castle O’Sullivan was built only for housing shows with very small casts. As others have said, the building is locked in by everything around it. I wonder if the AST would be able to receive an upgrade to bring it somewhere between the level of The Globe Theatre or The Moroccan Palace Theatre at Busch Gardens Tampa. It’s hard to say what could be done with the AST, because when you look at the tops of the towers at the front, you get the approximate height of the theater from basement level to above the stage.
I know it’s probably not feasible, and I don’t know if it’s even possible, but I would love to see the AST become a grand new theater, and COS brought to the current scale of the AST. I think the park made a huge mistake by designating their “flagship“ theater back to The Globe. That is very inconvenient location being at the entrance/exit area of the park. Still, in spite of the great amount of space above and below the actual stage, the AST is way too small to hold any modern Broadway-sized productions.
