I'm going to put what I said about this post here on this thread as well.
In response to that Reddit post, the problem with that is it could be devastatingly real in 100% of the way, or... it could be greatly exaggerated.
I in no way doubt employees have tested positive for the virus. By this point, it's not even close to a surprise. However... 12-20 PER ATTRACTION? I don't know. It seems everyone believes this post here but this is one post with zero sources of quite literally anything. It's a guy spewing out stuff. Again, I by no means think that is 100% fake, a lot of it is possibly truth about many testing positive. But at the same time a lot of it could be a stretch.
This very much sounds like it could be something like Seaworld since it does mention a sister park (Busch Gardens), and it never exposed which park they were talking about. Definitely not Disney since it just opened. Universal... has 3 parks around, and they've been doing better. Remembering how Seaworld and Busch Gardens are the ones doing pretty bad mask enforcement wise and sometimes distancing.
