I have heard it said repeatedly on a certain WDW blog that they are confident that WDW does not have outbreaks because there have not been any major CM outbreaks. But I don't buy it because guests often engage in more high-risk activity than CMs. Guests have to take their masks off to eat indoors at most WDW restaurants (most do not have outdoor dining) whereas CMs working in restaurants constantly wear masks and face shields.
I live next to WDW and many of our friends are CMs. It’s not public, but there are huge outbreaks of Covid right now among the CMs at DHS and MK. Galaxy’s Edge CMs got hit hard. However, they don’t believe they contracted the virus at work-many of the CMs gather after work together and there’s been quite a few parties. There’s a lot being kept hidden here in FL. We still go to the parks, but we are extra vigilant.
