I think this is a good thing, and if you allow me a minute to diatribe and monologue here (with some pure speculation) I can get to why:
Cedar Fair has long kept their parks in different 'tiers'. I've considered California's Great America, Carowinds, and Cedar Point their 'flagship' parks. Nicely spread through the country. At the bottom end you got Michigan's Adventure, Dorney Park, ValleyFair. They tend to get the "hand me downs" from other parks.
Kings Dominion, Kings Island, Knotts, and Canada's Wonderland all live in this middle 'gray zone'. They are big enough and important enough to CF to not get the 'hand me down' rides, but at the same time, they have to do some work to ensure that they don't end up stepping on the toes of the flagship parks.
Ok so we know all of that.
My 'speculation' as to why I'm liking this:
Clearly that middle zone is really muddled up. It's becoming harder and harder to keep attendance up without having to do something groundbreaking. Planet Snoopy was great for the park as it helped with attendance without being something major.
The best way (IMO) for the park to give the 4 mid-tier parks some breathing room to add rides without stepping on the toes of the flagship parks? Find a way to make the flagship parks a 2-gate or 2-day destination. An expansion to SoakCity - Cedar point; do the same thing with Carowinds. I admit doing this with CGA is much more difficult because of space and where the SoakCity is, so make it a 2 day attraction in order to do everything.
Now, you give the 4 mid-tier parks breathing room.
So getting back to why this new VP and GM thing is good IMO:
He's moving from a main HQ position to the park, which to me shows they have a long term vision for this park and where it's going. With the speculation I would hope for, having a guy from there that knows what the plan is can really make sure this goes smoothly.
Even without that, I like this. I think that CF would admit that the PS announcement was a bit of a disaster and that it was 'egg on the face' for KD to push like that. So having someone in that understand the scope and picture of what they want from the corporate level isn't a bad thing at all.
