Jurassic World: Dominion was originally set to be released on June 11, 2021. I'm sure when Velocicoaster was in development, they were planning to open it alongside the movie like GOTG:MB was opened near when GOTG 2 was released (kinda, 3 weeks apart but eh same thing) but then the movie got delayed in Oct 2020 so they couldn't delay the coasterNever know June 10th 2022 is the Jurassic World 3 movie release, so was just a guess for me. They can have a year of movie hype with this.
Far as the hours, I could see them being close to 2019 operating hours just as they have for this spring break crowd. Heck Mardis Gras is extended again.
