We just returned from a week at Disney. Our almost 3 year old granddaughter was a real trooper with wearing her mask. I was very concerned before we went. One reason I think it was easier than I expected: Everyone is wearing one. I think they see that and it makes it easier for them to understand they have to wear one. I was so pleasantly surprised to see people not trying to cheat the system. I honestly never saw anyone without a mask, or mask pulled down unless they were in designated areas. While wearing a mask at disney is not ideal, the lack of long wait times made it worth it.
