Theme parks strictly enforcing masks represents the ideal environment for reducing COVID spread. It's been said many times that at least an 80% compliance in mask wearing can result in cases dropping by 92%, and as we saw with the low case numbers from protests, that finding holds a lot of truth. Take those statistics into theme parks where you will find maybe 5% with their mask down to eat or drink in park walkways, and you've practically stopped COVID's transmission. HOWEVER, there are a few tiny details that can affect those numbers:
1. If you're not social distancing and by someone eating in the park with their mask down, the risk goes up
2. Restaurants in the parks have no efficiency in reducing spread unless there's ample outdoor seating, and even then, team members are not protected
3. If a mask slips or comes off on an indoor ride, there is a very small but not impossible chance the virus can linger through the building's AC depending on circulation flows
Going to the parks and not eating at restaurants gives you a minuscule chance of getting COVID. This is why I felt comfortable attending Universal's AP preview. However, I'm reluctant to go back to Universal or Disney until FL cases fall back down again because the daily number of new cases is higher than, if not double, what Uni's daily attendance is, and that's with an insufficient level of testing. Adjusting cases up to the probable total, somewhere between 2-3% of Floridians have contracted the virus in the past month, which means 2-3% of guests inside a theme park have COVID. That's a large enough number for me to be concerned about one slip up happening. You're about 90% less likely to get COVID inside a theme park than somewhere like a mall without masks enforced, but when local cases are so high, it's already an increased risk.
