I totally respect anyone who doesn't feel comfortable going to a theme park or even working at one, or anywhere with large quanities of people. That said...
I have a germaphobia. A true germaphobia for which I take anxiety meds. The really awesome thing for me is that Covid changed almost nothing about my behavior. I already had rotations for food based on when I bought it and dozens if not hundreds of rules for everything. You wouldn't know it most of the time to look at me because all of my rules allow me to behave quite normally.
I believe that with masks in place for both cast and guests that we will be as safe at Disney as we would be anywhere else, excepting perhaps my own large, rural, yard. My understanding is that transmission, when all are masked is incredibly low and that is why I'm okay with taking this trip. Also, because it is not considered to be a gastrointestinal virus (and, trust me, I have rules for that, too).
If people are careful and scientific. It can be a safe and fun trip. Weird, maybe. Hot, probably. But, safe and fun.
