Now that I think of it, this reminds me a lot of what Kennywood did, and suddenly it makes a lot more sense.
The idea here ISN'T to turn Dutch Wonderland into a major theme park, instead the idea is to keep somebody ELSE from turning Dutch Wonderland into a major theme park.
But it isn't that sinister, for evidence look at the Idlewild story. Idlewild is a park, not that much different from Dutch Wonderland, that is a short distance away from Kennywood. Idlewild is a huge park, that has decided to remain traditional and in fact most of their grounds are more scenic than ride populated. What rides Idlewild has are designed as whole-family experiences.
Dutch Wonderland is very similar, with containing a lot of whole-family rides, nothing too thrilling, as well as a lot of area to walk through and explore, including that huge garden in the back of the park.
It was once said that Kennywood bought Idlewild because it was close, and it had enough land that if someone wanted to, they could have reworked it into a major theme park. Which could have overshadowed and threatened Kennywoods viability, as Kennywood is a traditional park that does a mighty fine job of holding onto the past, while embracing the future.
I wonder if the same situation may have existed with Hersheypark, because a lot of the gardens and tranquil areas of Dutch Wonderland could be converted into a major thrill park. (And who knows if DW is holding onto a multitude of acres they aren't even using). I see Herhsey purchasing DW, maybe converting the Castle Gift Shop into a Hershey World and billing the park as a sister attraction for families with small kids. They may add some attractions but I forsee them keeping it as a more laid back children's type of park.
