I could honestly see The Vortex replacement in 2028 followed by a parking lot coaster (Invertigo/Congo/TW area) along with a renovated entry plaza in 2032 for the 60th anniversary (which is crazy to think we are getting close to the halfway point to that year as the 50th year feels like yesterday). Assuming we don't run into another major financial disruption (ie another pandemic or major recession or even bankruptcy).
"A new six-story hotel tower in front of the current hotel building, facing Kings Island Drive.
The hotel will have 24 three-bedroom suites and be connected to the existing hotel.
The hotel will be 75 feet tall, as tall as the waterpark, and will be visible from Kings Island Drive.
Removal of 55 parking spaces to make room for the new tower."
