Here's what I said about them in a different thread about a month ago:
I work with Fortune 500 companies designing business systems. Trust me, making sense is not factored into business decisions.
I agree with you that a FP only queue would limit standby lines, but again, I doubt Disney would go that way. Another possibility is that we see virtual queuing coming into play. Virtual queues would keep the people from physically lining up. But they’d have to address the massive morning crowds that Rise sees right now. Maybe allowing BGs to be selected from anywhere, as long as you hold a valid ticket for that day, instead of having to already be in the park. Non-PH tickets could be set to only allow you into the same park as your FPs, or maybe your first BG you get sets your park for that day?
Either which way though as much as I fear to admit it, there’s a strong possibility the parks don’t reopen any time soon when social distancing is still a factor. If I’m wrong, and I really hope I am, then the only way it would be viable is at limited capacity. Ride capacity would have to be running at a fraction of their normal throughput, in order to allow for sanitization between loads of riders. And to achieve that, Disney would have to man the rides with excess CMs to accomplish it. Less revenue vs higher expenses is going to be weighed against potential brand tarnishment of keeping the parks closed. Loss-leaders like that are never planned for long-term. Just not viable to the business. So, more likely than not, the parks will remain closed until the pandemic is suppressed, at which point it might just be back to business as usual, with maybe a few extra precautions.
It's still a way that they COULD make virtual queues work. Basically, you'd only get one 'virtual' queue at a time, and to avoid RD issues, you can get into the 'queue' from anywhere, as long as your ticket is good for that day. Non PH tickets would be locked to the same park, other's would be allowed to hop.
An alternative would be to implement a variation of the paper FP approach. Put an FP scanner at the entrance of a ride's standby queue, you walk by, tap, and get in the 'queue'. Your
MDE will let you know when to return to get into an actual standby line. You can only be in one 'queue' at a time. If you tap another one, it's like you left the first queue and entered the second, starting the process over again. The problem with approach is that it doesn't prevent RD, and I could easily see them ending up with real lines of people waiting to get into the virtual lines. Still, there are several ways it COULD be implemented.
But, like the OP, I don't think we'd actually see it. All a virtual queue would do is promote congregating in other locations around the park. More likely than not, it will be using the standard queues, with 6' markers, and limited capacity. Based on what they've said of Shanghai, it doesn't seem that they'll be sanitizing between groups of riders, just that they're going to increase sanitization schedules. Which pretty much makes the whole thing a bit of fluff. Even keeping your distance, a rider who gets into a vehicle right after a rider who's infected, will still be taking a risk of getting infected themselves, as the virus will still be present on things like the grab handles, seat buckles, etc...
So, the best we can do, until there's a vaccine or total eradication, is just be conscious, try not to touch too much, and wash/sanitize often.
