This would also be the problem with Fes/Expo USA. There's plenty of places that could accommodate 12-15,000 viewers at once, and tons of convention centers all over the USA.
The problem is finding one that is within a 10m walk of both of them - NYC has Javits, but it's 25-30m away from Radio City even by train, the Barclay's arena is further.
Boston has the BCEC, but TD Garden is 25-30 minutes away via the subway.
I'd personally like to see them do Friday/Saturday/Sunday, since you could schedule a stage on Friday night, and have more time for the Expo stages on Saturday Sunday.
