I agree with this, and would like to add that Kings Island was a pass heavy park for years before we "stopped" receiving interesting things. (The park is still getting good major investment, the stoppage/slowing mentioned is simply a sentiment many have shared on here and other social media sites.) I'd argue that Kings Island is the status quo that Carowinds and other parks are being told to aim for in terms of attendance and quality, while KI/SF management are firmly content with where the park is now. This is naturally leading to a feeling of stagnation since the focus has been shifted. If the park wants to think outside of the box for new events or update their current ones then they'll need to find a way to increase guest interaction without forcing them to pay $20 each time they visit the event. Unfortunately I think the company will try to use whatever they can to pay off debt, so events that change from year to year like the ones at Dollywood are out of the question for now.
Most passholders will probably be fine with lower quality because KI is their home park and is a family tradition. Families feel the price of a pass is worth it, even if they only ever visit twice. If they take a year off it might be hard for the park to regain their trust, which is why it's important to at least keep the status quo.
In other news, the Royal Fountain is being filled for the season. Does anyone know how they fill it? It looks like there are a few hoses being run into it, but I feel like that would be inefficient way to fill such a large basin. There was also someone working on a few fountain sprayer nozzles earlier today. I wonder if they'll reinstall the park sign after it's done being filled or wait a little longer.
