I think I can say with some confidence that we will reach herd immunity before the 50th. Disney probably is itching to loosen restrictions before then.
Not sure how confident I’d be in that. But I do think it’s very possible.
And I’m also totally positive that restrictions will be loosened before them. We already know a socially distanced FOTLK is coming back over the summer.
But it’s telling that the 50th Anniversary promotional videos still show people on masks. WDW expects masks will still be in place, at least at the start of the 50th.
