SeaWorld San Antonio and the two Texas Six Flags parks will continue to limit capacity and require face masks.
Gov. Gavin Newsom's team visited Disney World weeks before issuing guidelines that have kept California theme parks closed.
On the plus side, per capita revenue, admissions, and in-park spending increased in 2020.
The event will start March 18 and run on select dates through April 5.
The park will be taken over by Herschend Family Entertainment, the company behind Dollywood and Silver Dollar City.
Several parks' reopening dates depend on government COVID-19 guidelines.
Six Flags Magic Mountain and Legoland California both announced new, ride-less events Thursday.
