So I was just there 10 days. I've been 45 days since re-open in July 2020. This is BY FAR the most crowded and flippant I've seen both Disney and guests about abiding and implementing Covid rules.
Other than pseudo-masks, distancing is all but gone. Common areas are packed and markings to "wait" in queues are being ignored. People just don't care and don't think rules apply to them. The guests are far worse than 6 months ago.
Many rides operate at full capacity...7DMT, Thunder Mountain, Everest, HM, and many others have little or no distancing.
Masks are worn, but not enforced as aggressively, particularly at EPCOT. Cast Members used to stop people from walking and eating. No more. It's constant. Masks are consistently worn improperly. Boardwalk area has almost no masks. People take off masks during shows like Carousel and Soarin'.
Honestly, Disney is still trying their best I feel, but it's impossible to actually police this stuff all the time. I think CMs are understandably tired of reminding guests and corporate is feeling pressure to get capacity up again. I don't really blame anyone. If you're scared of Covid, stay home. It's still better at Disney than your average place.
