I'm taking all of this with a grain of salt. If masks are dropped great, but Newsom said when he implemented the theme park guidelines that they weren't park of the tiers, although the restrictions were tied to the tiers. The infamous "green" tier never made an appearance despite lots of references to it. I could see theme parks still having more restrictions than the state in general since it brings people from around the country and around the world, to it's gates and mixes them together.
I disagree. I think he is done lording over theme parks. It's already too late to enact new guidelines just for them after he repeatedly said they will be lifted for all, except very specific INDOOR locations with dense crowds. Theme parks don't meet that classification.
The parks are already only loosely following the guidelines anyway. The horse has left the barn, so to speak.
