How can one do social distancing in any of their tiny-aisle stores, or shoulder-to-shoulder queues? How can many of the rides have a decent capacity if guests who are not 'with each other' can't share a ride vehicle or bench?
Restaurants can space people out by using only half their tables, but how can they prevent the waitstaff from breaking the guests' bubbles of protection... and going from guest to guest to guest? Are they going to sanitize their hands before and after approaching every single table every single time?
And if quick serve is the answer, how are they going to enforce people in line to be 6 feet from one another? A line of 10 people at a mobile order window will be 60 feet long.
A hundred people in a queue for anything would require 600 feet of queue-space.
Are buses that pack in 80 people only going to carry 20 each trip? Is Disney going to quadruple their bus fleet?
Opening the parks for something things (rides) but surgically removing 'the real threats' (fireworks and parades) is a pipe dream. Almost everything the parks have to offer require continually breaking the 6 ft bubble. And even if you can maintain that social distance, is Disney going to wipe down the Seven Dwarfs Mine Train every single time between reloads?
Oh, and if this or any other CoronaVirus situation discussion is just a thinly veiled excuse for wishing or saying "Bring Back X!!".... not going to happen. The CoronaVirus situation isn't going to bring back Wishes or Mr. Toad unless it saves them money. And resurrecting old shows costs money. If anything, we'll get bare bones minimalist new shows. Bring back Wishes? OK, how about at half the length of the old Wishes as they cut out sections?
As long as enforcing social distancing is a thing to 'flatten the curve', the parks will be completely closed.
Except for golf and foot golf.
