I dont even think the PR was even that bad. They got the initial bad press for opening up, but that was to be expected whether they opened in June, July, or March 2021. The narrative would have been that Disney was opening too soon no matter what.
I dont fault them for waiting the extra month to make sure that they had everything in order. They have more to lose as far as public perception than Universal does just because of name alone. Did they open at the best possible moment? No. But there was no real data when they announced that date to know full well that Florida would be in the middle of a spike. And they were too far into the planning that it would have been irresponsible of them as a publicly traded company to push it off any further. They were comfortable with their protocols, and they opened up, and it seems like they made a good decision. Attendance isnt the best, and it looks like its going to get even slower in the next few weeks, and with reducing the hours, and (rumored) closing AK/Epcot for 2 days a week each, they seem to be preparing for a dip in demand.
