I took a solo trip Sep 24-28 - my second trip back since the whole Covid thing. My first trip over 4th of July weekend was when all mask requirements had been lifted for vaccinated folks, but there were still more things closed or canceled, so though the trip was fine, it felt like Disney being run at 2/3 speed - and passing so many restaurants closed, bus stops to resorts empty with those resorts closed, boat options in some cases stopped, etc...was sort of odd. There was still mask requirements on busses, and compliance seemed to be 100% around me at least. For September's trip, more things were open, and the overall feel seemed to be closer to normal Disney, though the mask requirements returned for indoor spots...again, compliance seemed very good - close to 100% around me at least...I admit I didn't go in as many indoor locations mostly just for the inconvenience of putting the mask on and of constantly, with a sweaty face in September heat...so I stuck to things I really wanted to do or see - the mask requirement became a good decider on how much I really wanted to do something.
I felt Disney was doing a nice job of cleaning. I saw more employees who seemed to be roaming in the seating areas of the quick serve seating areas, cleaning the tables and chairs before another party sat. And though the crowds were very high, and there's no social distancing requirements or enforcement in lines, I was able to just hang back from the person in front of me a bit, and most times, whoever was behind me saw that as a hint or a good idea, and would do the same courtesy behind me. Not always, so some fair warning that if you're really worried about someone getting in your space, you're probably going to have some uncomfortable moments. I will admit I'm less bothered with crowds/proximity than some others may be - most of my distancing is done out of respect for others, as opposed to for myself.
