Remember "Capacity" for USF pre-COVID was close to 50K. And they rarely hit that. The parks mostly run at 40-60% "capacity". Summer, the Holidays, and Spring Break were the only times they actually came close to capacity.
That said, aside from today's numbers, I am hearing REALLY positive things about how things things are going all over Orlando. Westgate is sold out through early Jan. Universal are opening Portofino and Dockside months earlier than projected. Disney is opening more rooms and dining across the resort. Things are happening because demand is there.
