I would come ready with layers because you never really know.
I live about an hour away (near the coast) and our humidity has not arrived yet. Our weather is glorious right now (though a tad chilly in the evening). It was downright cold last week. Orlando doesn't get that seabreeze so it can be different; best to check the days just prior to leaving and still throw a couple layers in the bag just in case.
I wear a cloth mask 100% of the time, and did all summer at the parks, without an issue. I do not like disposable masks at all. In July/August/September, I switched them out more often. I haven't had the need to change them out as often since October-ish.
