I didn't but my BIL tested positive on NYE and his trip essentially came to an abrupt end. We were around so many people coughing and not even covering their mouths. Also witnessed many gentlemen also choose not to wash their hands after using the restroom (that's true everywhere, not just Disney). Who knows when he contracted COVID...it could have been on the plane ride down for all we know, or our first day at MK, or at the hotel, etc. We will never know I guess.
I wish everyone would just cover their mouth when they cough or sneeze and wash their dang hands. It's the least we could all do to help keep each other healthy.
