You are assuming that they are using all three Exhibition Halls. They may not. The main ball room in Hawaii was 24,720. The largest ballroom in San Diego was 34,122 sq feet.
Ballroom A, B & C for sides/open play + Exhibition Hall A for the main tournament will likely be plenty of room.
I can't see the square footage, but they had all of Sapphire and half of Indigo IIRC.
I'm always of the opinion that more space is good space. For Worlds in North America, I'd like to see much more space than the Bayfront. I felt like the Bayfront was rather small for the event. It'd be nice to run a few more of those 8-mans over the course of the weekend.
