On one level, like a few other folks have mentioned here, so few people wear masks there right now that if you do, you get lots of weird looks; I mean, even in my area (far from Florida), I've had people intentionally cough on me and and that sort of thing when I'm the only person in a store wearing a mask. It's simply very awkward. (I'm vaccinated but have continued wearing a mask as Delta spreads)
But I'm also just thinking about how angry people will be if they're asked to go back to it at WDW. My family was *attacked* while in the Little Mermaid queue on my last trip by a group of anti-maskers making fun of my mother-in-law for wearing her mask... and that was when there was still ostensibly a mask mandate in the parks. If the mandate comes back, I'm afraid there'll be some nasty scenes in the parks.
