Once I become the owner of Kings Island, here's how it's all gonna go down.
I'd make The Racer go backwards again during my first season. Then I'd start making plans for the rest of the park. I'd get rid of Tower Gardens and split the area between international street and Oktoberfest. On the Oktoberfest side, I would add a topspin ride and on the international street side, I'd add a shop or a restaurant. I would keep Backlot Stunt Coaster because even though it sucks, it still is a people eater. I would add some more flat rides around the stunt coaster property and also one behind the international street showplace next to Diamondback. No more starlight spectacular. I would get rid of WindSeeker because it is not really a popular ride and it is always down. I'd invest some money in the train ride and bring back the old scenery. I'd also invest in an X-Base. Also I'd keep the peanuts characters. Over the years i would add some coasters. In 2022 I'd add a B&M giga in X-Base that goes 350 ft dropping an extra 100ft through a valley dropping at a total on 450 ft.
That's what I'd do.
