Well, if there are infectious people keeping them in one park limits the number of people they come in contact with to a smaller group. (Though not small, by any means. Even in just one park, )
On one hand, I haven’t heard of viral spread being traced back to WDW, so that would be an argument for park hopping. If you’re not passing it on at one park, no reason to think you’d pass it on by going to 2.
On the other hand, sometimes when community spread increases activities that used to be relatively safe and low risk end up being more moderate or even high risk. So to decide to reintroduce park hopping when community spread is probably at its highest seems a strange idea to me.
I hadn’t really considered the increase in dining by having larger numbers at Epcot at night, but that could be a factor.
@darkmite2 Sorry if I’m misreading your post - with the wink I can’t tell if you’re joking. But I do think they’re concerned. Otherwise, why would there be safety measures at all? And why would they be enforced by the CM?
