I disagree. There have been tons of people complaining about masks all over Disney FB groups and even on here. Many of them are the people going out to bars right now and will be going to WDW in the coming weeks and months. Many of these people have not been wearing masks at home.
For me, going to a theme park right now is unfathomable and a totally unnecessary risk, especially with a high risk child. Even if he wasn’t high risk, we still would not feel comfortable going to a place like WDW, especially with FL in its current state. I still don’t go to grocery stores or home improvement stores. Simply no need when everything can be done via pickup or delivery. Everyone makes their own risk assessments, though.
IMO, I also think there’s a difference between a 20 minute run into a store and 8 hours of continuous exposure in a theme park, removing masks for eating and drinking, using public restrooms, touching multiple ride surfaces, etc.
The outbreak of cases is likely from everything. Overall relaxation about the virus and people diving back in to daily life and not taking proper precautions.
