I would say in my 2 days at DS, I saw about 4 people total walking around without their masks and it was hot out about 93-95. I did see lots of people sitting down at tables, planters, benches having a drink or some food and not wearing their masks. Everybody looked to be enjoying themselves. People were talking and laughing with others, socially distanced. The World of Disney looked to have about twice as many cast members as guests. I do feel like this is one way that Disney is going to enforce the masks is by having an overwhelming number of cast members around at first. There is no way that World of Disney wasn't losing money hand over fist with the amount of labor on site. This was Friday and Saturday. People were out, but except for food nobody seemed to be buying anything else. Even when it was pouring down rain on Sat night, people still had their masks on. My wife and I walked from the B resort to DS with our masks on when it was 93 out, it was a 15 minute walk with 50 stairs up and down the pedestrian overpass (I didn't count them the security guard told me that's how many there are). I do not consider myself in good shape and the walk was fine, really hot, but fine. The mask did not cause any more discomfort than without a mask. We had the blue "paper" type masks that you can buy on Amazon 50 for about $23.
