This is totally based on my own feelings/instincts and nothing else. So fair warning.
I agree with you about Disney. I think masks are gone within a matter of weeks, if not sooner. IMHO, the biggest driver of keeping them was that they wanted the same policy at both Walt Disney World and Disneyland. Now that the mask mandate is lifting in California, I think they'll move to drop them on both coasts.
I feel like we are at the point where another variant/strain is not going to change anything. I think the masks are coming off and they're going to stay off. I think the calculus is that people are now comfortable with the risk level, given the access to the vaccines and therapeutics, and don't want to see restrictions be re-imposed.
I could be wrong. It's happened once or twice in my life.
But that's my gut feeling.
