I am curious, for all the "other surfaces" that aren't easily disinfected...walls, cabinet doors, shower curtain, etc...
If Disney could invest in some sort of high-powered UV light...drop it in the bathroom and turn it on while cleaning the main part of the room...then when you've done the main part of the room, move it out to the main area of the room, and turn it on while cleaning the bathroom.
5 minutes of high-powered UV light is about all it takes to kill COVID and one that is bright enough in the middle of the room should be able to reach most surfaces, even if some of it has to reflect off the walls and other objects.
At that point, a surface disinfectant for the high-touch areas (door knobs, faucets, light switches, phones, remote control, thermostat, etc.) to be extra sure for those, and you've probably got about 98% of surfaces in the room.
Another possibility would be "mist" disinfectants. They are using these at car washes in my area. There is a machine that turns disinfectant in to a fine mist. They ask that you turn your AC on full blast with the air on recirculate and step away from the car. They then blast this mist inside that gets propelled around by your HVAC and let it circulate for a couple of minutes. The mist gets itself on to all your surfaces, inside all the nooks and crannies, etc. Then they go at the high-touch areas with a surface disinfectant (screen, wheel, door handles, etc.) I could imagine something like this, just on a much larger scale. Get a large fan that moves a lot of air around the room, and essentially a "bug bomb" of sorts, except filled with Lysol instead of insecticide...lol That too would also get pretty much all surfaces in a room
