Have their China parks reopened yet? They were at least partially reopened as of late March. I have a feeling Orlando will start opening up by late summer unless things really hit the fan. We're getting into the phase where anyone who is at any risk will have to keep staying home, but everyone else is eventually going to have to or want to throw the dice.
Who knows about California. I could see them trying to go all year, but I understand that patience is also running out and even the most "liberal" areas will eventually have to open up.
Disney would be an easy place to catch the virus, but hell, you see how many people are crowding the public parks and beaches?
