Being concerned about the use of public bathrooms during an active pandemic is not paranoia. It's being careful and making sure you're taking proper precautions. Nevermind the response is just rude and isn't helpful.
Bathrooms are damp, people will take their masks off and they will congregate at the sink and mirror areas. Much as Disney might clean, they are not going to clean stalls after every use. I think concerns are justified.
I agree.
I was in a public bathroom last weekend--a necessity. Fortunately it was a large room, there were maybe 3 other women in there at the same time I was, and, interestingly, the doors to most of the stalls had been removed. One less thing to touch. Everyone was wearing a mask, but this is New York, and people here are hyperaware of the risks. No air dryers, just paper towels, although I'd brought my own.
I have no idea how WDW is going to handle this. Many of the restrooms there have a door to the room that you have to pull open, so there's no not-touching possible, unless you wait for someone else to do it for you--and then you aren't social-distanced. Many of the toilets (maybe all of them) have turbo-flush mechanisms, some of which are automatic. This is apparently a problem for reasons I'd rather not go into in a public forum. But, uh, human waste contains a hefty does of the coronavirus (if a person is infected, of course) and the turboflush tends to aerosolize this, spreading the virus throughout the area.
Further, the air dryers also aerosolize the virus.
So, yeah, I'm concerned too. I think the OP's paranoid is actually legitimate, measured concern. Paranoia is in another category altogether.
BTW, I didn't just invent all these ideas. They've been documented in several places. I read an extensive newspaper article about this a few weeks ago and I'd post the link, but it's a paper you need a subscription for. I'm sure you can Google this stuff.
