I really REALLY don't want to enter the great mask debate but I have a serious question. Assuming masks are a requirement... What about thrill rides??? I'm not sure a mask will stay on during Big Thunder or Space Mountain. I wouldn't want to receive a used mask across the face.
I don't know about your mask, but mine would stay on during Big Thunder, Space Mountain, Slinky or any other coaster I've been brave enough to get on.
I'm sure Disney will have a protocol though, because they certainly don't want a never-ending stream of e-stops from masks landing on sensors. They also don't want a bunch of people mask-less because they lost their only mask on a thrill ride.
