I think it's far more likely that mask wearing will be required, than not. Again, we're seeing it in other countries. I know there was a Canadian article last week that talked about the interim period between when we start opening up businesses again, but still don't have a vaccine etc...and still need to take certain measures, where they expect that wearing masks in public WILL be part of the requirements to open society back up. I know others have projected this as well.
I think people need to start getting past their idea of what's comfortable and convenient for them, and realize that life as they knew it is gone for the foreseeable future. That even when society opens back up, there are still going to be restrictions and requirements and changes to how we do things, whether they like it or not. And that will include at Disney as well.
