The weather and hurricane season aspect wouldn't bother me.
Ordinarily kids missing a week or two of school wouldn't bother me. I teach and still don't really have much issue with the odd week a two a year, in non exam years, tbh. However this year is different due to already having missed being in school a lot, and the two week quarantine needed after.
Apparently no outbreaks in Florida have yet been attributed to any of the theme parks, though it could just be time.
I assume the theme parks are fairly okay places right now if you don't mind the masks and other restrictions, I've been to a theme park during recent weeks and felt pretty safe with the stuff in place - and would assume Disney and universal to be ultra careful in comparison.
Lots of insurance now covers COVID once more.
However, not many cover you for when foreign office advice is essential travel only. And there is no way I'd visit the US without fully covered insurance.
We love visiting America and love the theme parks, but I wouldn't be heading there right now. We are not even sure it's going to be likely for at least another year personally.
