I think Kings Islands flat ride collection is rather small for a park of its size, not to mention almost every flat ride is located in Action Zone or Coney Mall. Some flat rides I’d like to be see added are...
S&S Screamin Swing, best flat ride in the world imo, it’d fit nicely in TRTR plot of land
Flying Canoes, this is a small family ride that Canada’s Wonderland has recently added, I think it’d fit nicely in river town
Mondial Top Scan, a high trill flat ride, it’d fit nicely into the parks flat ride lineup
Zamperla Hawk, another nice high trill flat ride, if it got a similar ride skin to Lumber Jack @ CW then it’d fit nicely into River Town
If it was possible (but I doubt it is) if Der Spinnin Kergs & Fly Dutchman we’re added back to Oktoberfest that area of the park would feel significantly better
I’m sure there’s lots of other great options out there but these were some options that I think are realistic to some degree, I hope the park does add more flat rides because atm KI only has 3 high thrill, non-upcharge rides.
