After the financial crisis of 2008, many people could not afford to go to Walt Disney World. After 9/11, many people were scared of air travel. But in neither case did people actually worry much about the parks themselves.It’s laughable to suggest a capacity RESTRICTION through 2022. Perhaps actual attendance will remain down due to a recession, as you say. During the 2008-9 recession, for comparison, WDW attendance plummeted a full 1% (one percent) and rebounded by 2011. After 9/11, it fell 5%. To suggest it will still be down 25% in 2022 is just silly.
With COVID-19, there is at least the potential that people will think that the parks themselves are unsafe. No, I don't think that will tank attendance by 25% or 50%, but you don't think it could be more than the 5% drop after 9/11?
