Except Disneyland's was held in a 18,000 sq ft ballroom and Disney World's is being held in an over 44,000 sq ft ballroom.
That will depend on whether they use the full-size Fantasia Ballroom, or partition off the 12 breakout rooms along the flanks and perhaps slide the walls across sections H or G, leaving just one or two of the 10,000 square foot center sections of Fantasia to seat the potentially smaller crowd.
One thing I know from the event planning industry is that planners and stagers absolutely
HATE to have a room that is bigger than the crowd, and they'll pull those moving walls of the Fantasia Ballroom closed if they can.
At September's Destination D in Anaheim, they set up the full 18,000 square foot Disneyland Hotel Grand Ballroom in the two-level auditorium seating plan, to accomodate the sell out crowd at $125 per person.

The Disneyland Hotel's full convention center is actually a bit larger than the Contemporary Resort's convention center, and they used the room and seating format that worked best for the 2010 Destination D presentations that were mainly on a stage flanked by four movie screens.
Disneyland Hotel Convention Center - 136,000 Square Feet of Meeting Space
Contemporary Resort Convention Center - 115,000 Square Feet of Meeting Space
At this point three weeks beforehand the tickets were sold out for the Anaheim version, but they are still available for the WDW version. A big part of that might be that they are charging $175 for the WDW event tickets ($215 if you want to do the scavenger hunt), which is quite a bit more than the $125 Disneyland version last September.
It will be interesting to see who shows up, how many show up, and how they divide up the Fantasia Ballroom if they do the stage presentation format that they used at Disneyland last year. But for now, the lack of buzz on this event is noticeably odd.
