Not so sure about this . . . I mean, I have absolutely zero clue when things will start to reopen, but I feel pretty confident that when they do, there will still be an abundance of caution for a long time after. COVID-19 is 100% here to stay. There is no way to end this virus, just like there's no way to end the flu or the common cold or anything else. The point is getting the pandemic under control, and getting treatments/vaccines/whatever in place at hospitals and within our healthcare system at large so we can treat it, just like any other virus.
Let's say, in three months, the curve has been sufficiently flattened. (Being optimistic.) Things will start to reopen, but COVID-19 will still be active. There are going to be lots and lots and lots of extra precautions taken in all facets of life, not just at theme parks. If the country waited until this thing became as benign as your average flu, the economy would be completely doomed -- like, irrevocably doomed. It won't get to that point. Expect things to reopen, but also expect a new normal.
