Irrespective of the months you attached, I think it is important to understand that whatever happens, it's in the best interest of the company, the the state of Florida, the entire theme park industry, and even beyond, to have the TWDC domestic parks execute a phased rollout plan. I think the best place for them to start with a ticketing base is to only allow AP holders in for a couple weeks to MK or AK, then open the resorts and allow only onsite guests and AP holders into the parks. Sure, you're talking about letting your lowest revenue guests back in the gates first, but the company is already forgoing payment on month to month AP plans and losing out on any potential renewals or new purchases of said tickets. It's also going to be a virtually 100% in state populace. Ideally (IDEALLY!!!) it's also a populace that will be more patient with the massive changes in the status quo to operations (no theater shows, halving capacity at all restaurants, significant expansion of boarding group queuing).
A few weeks ago I thought of the idea of closing Epcot separate from the rest of the resort was ludicrous. With the intentionally depleted staffing, the size of the park, and the outstanding construction at the park, closing it through the summer actually makes some sense to me. I do expect a number of the resorts to stay offline through the end of the year (absolutely insane, talking about closing Disney resorts through Christmas!) I believe Port Orleans was closed after 9/11, so that and the All-Stars could remotely conceivably stay closed through Summer 2021.
The biggest factor, and the one that is impossible to predict right now, is when and how can the crowds come back? This is a good time to have a company full of bean counters to game that out for the resorts. I can't imagine what that looks like.
