The wife and I went to Hollywood Studios today. We arrived at the parking booths at 9:15, and there was quite a backup. We got through at about 9:35. Even though there were tons of people, we got through temperature check, bag check, and the entrance very quickly. We found a shady place to sit and waited until 10 to try for a RotR boarding group. Much to my surprise, we got group 1! We went straight to the ride and were probably one of the first 5 or so groups on. We loved how the cast members stayed in character with all of the virus stuff. One First Order guard suggested that we sanitize our hands, and as we did so he said now he was definitely going to lock us up because it looked like we were planning something evil (rubbing our hands together).
Mask compliance was much better than the absolutely terrible situation at Epcot yesterday. Still way too many jerks with their masks off or below their noses, but probably only 1/3 as many as at Epcot yesterday. Hollywood Studios was extremely crowded compared to the other 3 parks, and at times it was difficult to social distance. I had to tell a few people to get away from us after they get way too close to us, included one pair of ladies that sat right next to me on a bench. I also had to tell a few people that were right next to us in line to wear their masks. They would typically whisper to each other right after I did it, clearly talking about me. Yeah, I'm the jerk in that situation. Whatever.
We actually had a pretty great day. We rode RotR, Minnie & Mickey's Runaway Railway 3 times, Smuggler's Run 3 times, and everything else once.
At this point, I'd probably still be okay visiting every park except Epcot. We're done at Epcot until things change one way or another. In terms of feeling safe at the parks, I'd rate it Animal Kingdom -> Magic Kingdom ---> Hollywood Studios -------> Epcot.
