I haven't worn them at Disney, but have some in my rotation that I wear all day long (I'm a teacher) in combination with a bracket. For me, they're a little heavy alone and I don't think I would be happy wearing them in the summer at Disney, but with the brackets they're fine (as are pretty much all masks). I tell everyone, the brackets are a must have for masks - they're more breathable, you're easier to understand, and they even make running at the gym with a mask bearable.
