I think there is a serious disconnect of what Disney is like if you haven't gone recently. Even before all this, I would hear comments from work colleagues or friends like 'Why would you want to go and just stand in lines all the time?' There's such an association that Disney=large crowds that's hard to dispel. People don't understand that even before the pandemic we had things like FastPass, touring strategies, etc. Most of the comments I hear that are anti-opening for Disney are from folks that don't usually go to the parks anyways so likely aren't familiar with how safe they're making it right now. Which is a good reason to get that positive PR out there so that negative association starts to diminish.
I've said this before on this thread but comparing theme parks to schools shouldn't even be a consideration. We feel safe traveling to Disney this winter but I don't feel confident in sending my 10 year back to his elementary school yet (if they even open) which is why we opted for virtual learning. The two scenarios are just so completely different. I've worked in education my whole life from K-12 to now in higher education and it's just waaaay more complicated.
