The situation is looking to me very similar to mid-March, where we are on a trajectory towards a tipping point in public opinion. We're not there yet, but it's just going to take a couple of days of bad numbers on top of the persistent messaging from health officials and we're going to get there. If Florida starts posting 10k/day numbers going into the holiday, that could be it.
This forum has debated the finer points to death and back again, and I personally see valid points of both sides. I think there is a path towards Disney being safely open in some fashion. Team #openitup has made a very vocal and valid argument, but it seems to me that they are rapidly losing ground in the court of public opinion and official guidance to team #shutitbackdown. If someone can show me a path in the current 'numbers' reality to have it both ways, that would be awesome... but as I see it now things are not going the right direction and it's hard to see that line changing for the better in the near future. My gut feeling is that if Disney does open, the opening will not be able to be sustained.
So you have to ask yourself which is worse... pulling it before everyone shows up, or... rolling the dice and dealing with the fallout if it goes south?
