We just got back from a trip 2 weeks ago. Most people were following the mask rules, but there were several who were not. Some were just forgetful from coming outside without wearing a mask and some were just not concerned about it at all. They would put in on long enough to get in and then just pull it down or take it off completely. To be fair, it was 100° in the shade almost every day so it was not comfortable in a mask at any point....But rules are rules.
IN my opinion, I believe Disney has seemed to take the approach of reminding people to put their masks on where required but not enforcing or "causing a scene" if people do not comply. I can understand their reasoning....The CMs are not in a position to be "enforcers" of a controversial and often heated subject. Moreover, I think everyone that walks through the Disney gates understands the current risk in doing so and while Disney can only do so much the responsibility of accepting that risk and coming to Disney during COVID ultimately falls on the individual guest.
