I really wish I knew how bad was Disney's "bad" LOL
I think it's safe to assume that it's really bad.
If I was guessing, something like this:
First it would get to a level that 25% of people think is bad, but not bad enough to change Disney.
Then, it would get to a level that 40% of people think is bad, and Disney will start to suggest changes coming.
Finally, it would get to a level that 45% or more of people think is bad, and Disney would start to do something, but nothing drastic.
Personally, I'm in one of those earlier groups, so I'll be worried about whatever bad is happening prior to Disney.
If I was also guessing where were are today, I would put it at under 10% of people think it's still bad right now. Probably under 5%. There's lots more that think it's "not great" now, but that's not the same as bad.
Hence, I wouldn't worry about Disney bringing back any mitigations efforts if that's your concern. Mitigation things will show up lots and lots of other places before they return to Disney. You'll have whatever is driving that badness to worry about then too, to take you mind off of whatever Disney is doing.
Things are a lot different today than they were back when Disney first reopened. Back then, they were doing things to attract people to come into the parks. A reopening from fully closed. Today, it would be the reverse, a move from fully open towards more mitigations. We've already talked about how Disney guests are a self selected population of people with a risk appetite that's likely larger than most. Nobody planning a Disney trip today is in the 5% that thinks it's bad already.
