The parks have been open for awhile with no hit to public perception.Ultimately, Disney is going to make a decision based on their capital reserves. If they feel they can endure the short term losses of either a mask mandate or a new park closure better than they can endure the long term effects of a public perception that the parks were enabling the spread of a deadly pandemic, they'll change their mask policy. If they feel their cash/credit reserves are not sufficient to weather that storm, they're going to continue to operate as usual with their fingers crossed and hope for the best. Of course, theres a third possibility, which is that the leadership responsible for these decisions are either inept, or ideologically incapable, of making a rational calculation here.
If the public was concerned about the virus you would see a lot more people wearing masks at the parks.
Heck the UK has opened back up right in the middle of the spike and we are gonna close down again?
Makes no sense.
