It appears the state of emergency declaration is a requirement of federal assistance. Renewal, possibly with some changes seems likely to me
I agree with PP, probably won't affect Disney either way.
FL ban on use of vaccination and/or covid test status could limit some options available to Disney.
Edited to add I suspect CDC guidelines allows Disney to limit medical exceptions.
Many Disney attractions worldwide have a FP entrance and a standby entrance. I can see, in areas where permitted, one entrance being used for vaccinated guests. That queue wouldn't require social distancing.
