I still don’t understand the thought that Disney needs to clean its transportation options after each use in order to function, or not even open some methods. Hand sanitizer stations before boarding and after boarding make sense, so does practicing good hygiene. Maybe lower the occupancy by a few dozen.
All over the US, mass transportation is still functioning with people on board. Sometimes it’s crowded, sometimes it’s not. Buses, trains, airplanes, subways.
Disney has operated under risk before, and they will again. I just see transportation as not a big issue for the Parks.
