Disney has a reputation built on being magical. You are a princess, We will make your dreams come true. This is a hard pandemic. Magical and pandemic just don’t go together. Universal has IP that is just the opposite. You are a superhero, You are a wizard, You can save the world. That’s much easier to do in a mask, though a cape would also be useful.
Disney may be sitting back to watch how others open first, but they have a different clientele. Those folks that do Disney AND Universal AND Sea World, they are awesome. They’d love to open to all those healthy small groups that roll with the punches. But Disney also has the Disney bubble guests: the three or four generation family reunions, the special needs families, and those families that believe in the magic. How do you protect Those most at risk: the elderly, the Pooh sized, the special need families in a pandemic? How do you protect those that think Disney is magic and the big bad pandemic won’t be found at Disney, and therefore their frail family members they won’t take to the grocery will be safe within the Disney walls?
I don’t know that Disney guests are less likely to comply with safety measures than those at other parks. I don’t think they are more entitled. I just think the risks of those infecting someone where the outcome is dire is higher at Disney. And I think they know that, and that is making them more cautious.
