I think the major issue for WDW is enforcement of compliance. When we are out in a pretty open area (like hiking in the forest) we are not wearing masks, but have them on hand to put on when we start to approach others.
Thing is, I don’t think that will happen in the parks. It’s either no mask free for all or masks all the time. I just don’t think people would be able to grasp the concept of masks indoors and no masks outdoors. Since we are continuously changing our location when you go in and out of attractions. I think that is why there is a blanket mask statement. I can just imagine all the people forgetting as they walk into the line for Thunder Mountain. Or even, is that considered indoors or outdoors? The queue line is kind of a mixture of both, right? When would the mask be needed in that scenario? It’s just so messy and confusing, which leads me to believe it will be one or the other. And for now, it’s masks everywhere.
