That's a bit exaggerated. It is definitely an issue and you will encounter some instances of inconvenience over it. If you are coming down in the near future I would think at least some beaches would be open, at least in the Melbourne-Cocoa area, which is less than an hour east of the resorts. There are reports of Disney workers asking Disney to hold off on reopening, so you might want to keep on top of that.
Fact is, coming to Florida right now is a bit of a gamble. I see some states have now instituted a mandatory quarantine for people coming from here to their states. Affect you? I don't know. And of course could change daily or weekly.
I will say, South Florida HAS been much worse for the virus than Central Florida. But, in the last week to ten days, Central Florida has had a number of hot spots.
