And if it's even only 90% effective, why bother? From a legal perspective, that 10% false negative rate is just one more minor hurdle for the plaintiff to jump, after the giant DLR-style signs saying "you may catch COVID by entering" and having to prove you caught in MK and not in Publix or on the plane ride down. Ultimately any "medical check" will be theater, like post-9/11security. Albeit one playing with highly regulated government data and potential to offend the ADA.

Unrelated, but over on Magic, Magic Feather dropped a bomb--Voyage of the Little Mermaid won't be re-opening--but also mentioned Frozen Sing-Along Celebration will be getting assigned seating like a movie theater.
Not surprisingly, it sounds like competing plans are on the table. This somewhat contradicts the Doomsday Scenario (which still foresaw an August opening btw). At the same time, it seems like no one at the Mouse is expecting capacity to be an issue for a while.

Finally a couple thoughts on a potential 2021 re-opening. Not quoting anyone because not trying to call anyone out, just something for all points of view to remember: nothing takes place in a vacuum.
WDW is a unique entity that owes its existence solely to Florida government--Reed Creek's autonomy and the DVC program (which is legally not timeshare) and its police service from Orange County, they all could be revoked with a simple vote. WDW has a close-knit relationship with state and local government, but it also risks bankrupting both of those every additional week it stays closed. Local Chambers and industry associations--who also have lobbyists downtown and in Tallahassee--are feeling this closure as well. That has to generate enormous pressure.
At the same time, unemployment benefits won't run forever. Even with generous extensions, I don't see them going 10 months. Even if they did, not enough to live in this high cost-of-living town. I already see a couple U-Hauls outside my apartment building every weekend, and they haven't given tours or opened the rental office in a month, so I imagine its people moving out, not in. I don't know how you begin to re-open the parks in 2021 if half your 70k workers have moved out-of-town.
This last point cribbed from a controversial YouTuber, but I have no reason to doubt it -- ISAW uses over 10k motors not including the boats and waterway. Imagine leaving all these systems, some decades old, unattended for 10 months. How many are actually going to start up again?
Literally every day WDW is closed it becomes that much harder to re-open. I don't doubt they will lose money for a while, but the logistics of running the park and the optics of appearing open for business mean they let people in the day their Legal team says it's ok.
