I agree the SW:GE park event could go on, considering the park is already open and running. I'm already on record about the timing of the event in general, so I won't repeat that.
As far as the panels, yes they could be virtual I suppose, but wasn't photo/meet/greets mentioned somewhere? Maybe in the FAQ? Anyways, it would have to be an epic event, and likely tied to music, to get me to stay indoors for an extended period of time. If I were to attend a panel, (assuming that masks are required to enter), you'd probably find me in near the back third of the room with binoculars while wearing a wrap/cloak or outfit that I can easily decontaminate afterwards. (So no "special dress" outfit for indoors)
Now, an outdoor walk on the grounds.... Why, yes! I do think a Posh Party Stroll would be lovely.
