Folks,
I can probably offer some insight here. I just renewed our AP, and asked the castmember how many days we have spent in the parks. Since reopening, we have spent 28 days there, mostly long weekend trips. Our first trip was in July of 2020.
Please do not miss understand. I do not like wearing a mask. I will do almost anything to avoid it.
On our first trip, you had to wear a mask anywhere on property. It was difficult, but we did it. We had a great time. At one point, I had to take a phone call from work. I went all the way in a corner, outdoors (in AK), away from everyone to take the call. I took my mask off to speak on the phone. A cast member came over to me within a few minutes to tell me to put my mask on. I complied.
Over time, as the mask mandates loosened, so did the rules. Previously, when on-line, while the rule was you must have your mask on, in practicality on most lines they only had you put your mask on as your got indoors or under a covered area. With socially distanced lines, that basically meant as you entered the buildings at Space Mountain or Buzz. At Rock 'n Rollercoster, it was when you reached the covered area. At Tower of Terror, it was as you went thru the "Gates" at the entrance.
On our last trip, no masks required at all for the vaccinated. My entire family has been vaccinated for months. I saw a lot of children on that trip that did not have masks on, and we know they cannot get the vaccine. However, back to my initial statement, my family is all vaccinated, so I really did not care what others did.
My point in all of this, we did Disney with masks in some form or another for 25 out of those 28 days. It is doable. It can work. Obviously we enjoyed ourselves as we kept going back.
I must admit, it was nice seeing everyone's smiling faces, even if it was rather short lived.
