I think whatever happens at Great Adventure is going to be the defining event for me of Zimmerman's era at Cedar Fair/Six Flags.
I've kinda gotten the vibe for a few years that, post Ouimet, Cedar Fair never had a strong sense of direction. Ouimet attempted to aggressively attract families while improving the value of what your ticket got you, which is where semi-themed new rides, non-typical shows (e.g. Cirque Imagine and the like), LARP-based experiences like Ghost Town Alive, (a mild attempt at) new dark rides, and higher-quality food offerings came from. Zimmerman at CF seems to have lopped off the more pricey parts but otherwise attempted to keep that status quo. Then COVID happened, and I feel like the goal was to position the company for the merger through cutting costs to make the books look good.
At this point, I feel like they've announced the immediate closure of a third of Great Adventure. If Six Flags and Zimmerman are serious about bringing a quality experience (to stay in line with the Ouimet philosophy), in my opinion, we'll see more than just a coaster in that area. We'll see!
