Cedar Fair is having to raise wages, step up recruitment and offer signing bonuses to fill available jobs.
The CDC still recommends that people aged 2 and older wear masks, but the Cedar Fair parks are only requiring masks for guests who are at least 10 years old.
The looser mask standards also mean guests do not have to wear face coverings while outdoor and physically distant from other parties.
The list includes California's Great America, even with the state's stringent reopening guidelines.
The $27 million resort will be called Kings Island Camp Cedar, located less than a mile from the park gates.
One of the barges for "Harmonious" will begin testing on Epcot's World Showcase Lagoon very soon.
The park chain has lost $484 million in 2020.
