We have a trip in a few weeks so have a bit of a vested interest in seeing present capacity remain as is. That said, I have some thoughts on this:
1. The 35% capacity issue seems to be self-imposed. As far as I recall, I think Disney has had the ability to go higher than 35% if it wanted to, but has not elected to do so thus far. So any Orange Co./ State of FL restrictions aren't what's kept Disney at 35% right now.
2. 35% of "capacity" depends on how you look at it. Does that number change based on hourly capacity? Can improving ride capacity - going to more rows on Pirates, adding separators to fill in a car on ROTR with more than one group, etc. - improve park capacity, and raise the overall capacity? I've heard rumors those sorts of internal adjustments are allowing them to remain intellectually honest to the 35% capacity number. So in terms of bodies allowed in the park on a given day, the 35% capacity looks different today than would it would've been in January.
3. Disney may not have the means to scale up past 35% right now. It sounds like they're trying to entice CMs to come back. There is a thought that operations are ramping back up. Many others with a far greater understanding than I in terms of park operations have said that the lack of shows/FP and even a reduced social distancing arrangement still makes the prospect of more people in the park pretty untenable.
Those are my general thoughts. That said, I feel like changes are underway and can see things changing come Memorial Day weekend / June.
