I don't think it is as simple as what the governor wants---or even what the company's executive leadership, board of directors, or shareholders want. What matters is what the virus does, in the context of how we behave.
The most likely scenario I think we are looking at, for at least the next many months, is what some folks have called the "dance" from this article:

The basic idea: once we get things tamped down, we will have to watch things very closely. Just because case numbers go down, that doesn't change the fundamental qualities of the virus. It is still highly contagious during pre-symptomatic periods or in asymptomatic cases. So, if we just go back to "normal", we're going to start all over again where we were in, say, February. Instead, slowly lifting restrictions plus very aggressive testing, tracing, and isolation will be the way we limp along until a vaccine is widely available. That's likely to take at least another year.
In that world, some things take longer to come back than others---and the more densely people congregate in an activity, the later it is going to come back, if at comes back at all before a vaccine. One of the latter things to come back will be cramming people into switchbacks in a theme park. Even if the parks are open, they will look very very different, because you just can't put as many people in them as you do normally. And, it might not be profitable to run them that way, in which case Disney would probably rather just keep them closed.
