This is what the science has been saying for all over the country. When people get together with family and close friends they tend to think that they are safe without wearing masks or social distancing. However, when they go to other places (like grocery stores) they will conform to the recommendations. So, in a place like
Disneyland where there are strict rules for mask wearing and social distancing, people are far more likely to follow the proper precautions. I think that is why we don't see infections traced back to that type of situation.
So, in fact, it would help if people could have an outlet for their covid fatigue in a safer way than family gatherings without precautions. Disneyland could be that outlet.
