No one thought on January 1st that every Disney Park in the world would be closed down for 2+ months.
im not saying they will, or are opening on June 1st, but they can re-train and get the parks ready in a week. First week of June reservations will begin to be cancelled within a few hours, so we’ll see soon. Not that it’s a pure indication, but considering they’ve been doing the rolling cancellations for over a month now, it’s the best system we can go off right now
As a former CM, I can most definitively say they cannot retrain and get the parks ready in one week. I'd be doubtful they could do that for one park, but for all four, there's no way. First of all, World Showcase currently has very few CMs in the area that are trained to operate it (especially attractions and full-service restaurants), so I can basically guarantee you Epcot will not be reopening alongside the other parks. Training can take anywhere from 5 to 8 days generally but can be longer depending on the line of business. While they wouldn't need to retrain CMs in their original work locations, they'd still probably refresh CMs in their work locations, and they'd absolutely need to test out new procedures as well as train their CMs in encouraging social distancing, enhanced sanitation measures, and other health and safety protocols (something they've already said they're committed to doing). And of course, if they do decide to shift people around due to absence of CPs, then re-training would be required. I also don't think it's a good sign that WDW is keeping World of Disney and other owned stores closed at Disney Springs.
There is also a level of prep work that has to go on to restart food and merchandise supply chains as well as get the park "show-ready." All of that would require additional manpower, which we probably would've heard about being called back. While WDW has been keeping up with maintenance, there is going to be some cleaning and other work done (like the stuff that's generally done overnight). That stuff will take a bit of time. Restarting WDW operations in this new normal isn't going to be just turning on the lights and throwing open the "gates" to parks we loved; there will be a level of prep work involved in preparing open this new version of WDW, one with an increased focus on sanitation, health, and personal space. It takes time to get the temperature screening tents set up and tested; it takes time to get the little "stand here" stickers measured and applied throughout the parks.
Again, I'd point to Shanghai where there was about a 3+ week period in between when CMs were back at work and when the park reopened. While I think our prep period may be a bit shorter (assuming the various measures put in place in Shanghai prove to be effective), cutting that down to less than a week seems unrealistic.
I don't mean to be a Debbie downer. I would absolutely love, love, love to be wrong, but I'm also looking at it from a practical standpoint, and there's a lot of operational challenges that need to be addressed. I give it 0% chance of all parks being open on June 1 and a 10% chance of at least one park being open. Like other have pointed out, Disney could call the CMs back and "break" the schedule, but I don't see Disney doing that, given the delay we already saw with this week's schedule posting.
