Are there any people eating attractions or shows still closed? Or, not running at close to full capacity? Especially indoor stuff?
How about restaurants? Any that are entirely closed, vs reduced capacity within one?
My guess is that they're not going to reduce any overall capacity at all. The most they are likely to do is require indoor masks and then pack in full loads of people for all the indoor stuff. For restaurants where you cannot mask, they might bring more locations online and spread out capacity among them. Something like having the full restaurant location capacity they would have at peak with the reduced park capacity they have now (even if it's not reduced much, its not the same as super full day), allowing them to spread out and have less capacity in each location.
It's clear by now that masks beat out distance. If you're only getting one, it's not going to be distance. Despite what people may prefer.
As someone else pointed out though, they're not likely to do anything unless the risk of bad press gets to large. They've adjusted to "it's over" and most of the guests have too. Doesn't matter if it's over or not. Those who haven't just aren't going now. Demand has never been a problem, there's still enough in the "it's over" group no matter their vaccination status.
