I think Remy has said that Disney’s choices regarding the opening were made so they can remain open during spikes and future waves, right? If it gets really bad I do think they’ll delay, but with a reservation system (well if it ever comes lol) they have the ability to control entry and numbers into the parks, and they can obviously close various things at their discretion.
So more of the same, if you’re still comfortable going when things get worse instead of better, be prepared for a lot of unknown, possibly having to cancel plans without a lot of notice, and departure from a normal Disney trip.
