Our first Epcot day was Saturday the 18th, and then Thursday the 23rd. The 18th was a little more crowded than the 23rd, both days had some rain, but Thursday much more. So that may have contributed. We never saw big groups of people without masks except at Disney Springs. We did not feel safe at Disney Springs at times. I contacted guest services over the app chat and emailed them about it especially a bus situation.
We did two HS days as well, it certainly was the most crowded of any park, but mostly in Galaxy's Edge. AK was the best as far as low crowds and fewest people not following protocol. It's surprised me how much more I enjoyed FoP not having to wait in a long line. It may be my favorite attraction again. RotR is great, and I am a Star Wars fan, but FoP was more fun.
