The continued overall investment into park infrastructure and major maintenance of aesthetics is something that sets Kings Island apart from most other parks in the chain. All of the general maintenance is also what keeps KI from taking 5+ years to do something like restore their carousels as Six Flags St. Louis did.
I'd argue that some of the points made are reductive since, looking at the entirety of projects for some of the given years, the park went far beyond what could be considered annual maintenance and upkeep. I also think there is a lot of truth to the matter, so it's not an absolute truth either way.
2018 Coney Bar-B-Que replaces Coney Potato Works and the Attitudes gift shop. Kings Island begins to make vast strides to improve food quality with the appointment of cooking champion Chef James Major as Executive Chef of the park. While not many additions are seen at KI in 2018, other major investments in the chain are opened. Firehawk closes to make way for a future roller coaster.
2019 Kings Mills Antique Autos replaces the now-defunct Dinosaurs Alive! entrance and gift shop tent. International Street also receives an extensive renovation to replace its aging infrastructure and make way for new passive show opportunities. Miami River Brewhouse opens in Rivertown. Grand Carnivale debuts as the park's newest festival event, and takes advantage of the new parade route on I-Street. A new daytime event called Hallo-Tween debuts for guests too young for Haunt but too old for The Great Pumpkin Fest. Halloween Haunt introduces four new scare zones and one new live show. I have some major gripes about the I-Street redesign. Trees and shade are something that KI already needed a lot more of, and this major renovation removed all of them. There are so many things I'd have done differently, but I have enjoyed the new sightlines the refresh has allowed. KMAA are also more lackluster than the originals, but there is no way we'd see anything like the originals come back unless the Stunt Coaster were to be removed — something KI could not afford to do having removed Firehawk and being close to removing Vortex.
Vortex closes after 33 years of thrilling guests with no apparent replacement in sight.
2020 Orion opens as the world's shortest Giga Coaster, while still being the tallest and fastest roller coaster at Kings Island. The park opens in July due to the COVID-19 pandemic. All seasonal events were cancelled with the new Tricks and Treats Fall Fest replacing The Great Pumpkin Fest and Haunt for the season. 2020 was a bad year for everyone, but I enjoyed that I was still able to go to the park and that we didn't have to buy new passes for 2021. The little troupe of cleaners that put on their short show was a nice surprise for a season where all entertainment had been cancelled.
2021 Still feeling the effects of the pandemic, Kings Island steadily returns to normal. I particularly enjoyed all of the small-stage entertainment options and wish some of them could come back full-time. The fact that a lot of the new things from 2019's Haunt didn't return was really upsetting.
2022 Kings Island celebrates it's 50th anniversary season with extensive restorations to the park, including a full restoration of the Grand Carousel, new paint on rides, extensive historical displays, exclusive food options, and new shows that celebrated the park. Miles better than KD's 50th celebration with a ton of awesome stuff. Probably the peak of KI memories for me.
2023 Adventure Port opens mid-season with newer versions of Der Spinnen' Keggers and Skylab. Two refreshed dining/drinks options move into the former Biergarten and Adventure Express receives more theming.
2024 Half-baked revamp with Camp Snoopy I have to agree with this.
- Cheapest coaster they could get by with.
- Cheapest play area they could get by with.
2025 Cheapest Water Coaster they could get by with. RiverRacers may be the cheapest water coaster, but I think Splash River Junction and the surrounding area refresh were well needed. The 5 restrooms being renovated across the park was also really good.
That all being said, I do agree with the sentiment that these companies have not been investing as much into Kings Island projects as the park deserves. The budgets did appear to get cut big time and the park has not been doing as well for guest service as it used to IMO.
