Eh, I’m not sure that’s going to matter enough for Disney to pull mask restrictions. The parks are just one part of a massive empire and at this point they have shown that they would rather err on the side of caution, even if that comes at the expense of park revenues, which I think is probably the right move. Disney has a bunch of other revenue streams to rely on, particularly
Disney+ at the moment, but they also know they could face consequences if the parks become a transmission vector for Covid that other companies like US or Sea World wouldn’t.
Also, unlike a lot of the other parks, Disney has the ability to eat losses for longer because they have other ways of making money. The parks were essentially money making machines pre-covid and I think Disney would rather take the hit now so there isn’t any event that could prevent the parks from returning to that once things get back to normal. Sure, they might lose a marginal amount of business to the other Florida parks for they remain more strict, but they know that WDW is a valuable brand worth protecting in the long-term. They aren’t going to throw that away for one year of lost revenue on the parks, especially when they have other revenue streams.
