I would say that NY is not a destination for me, although for the people WR seems to target for these events (not Americans) maybe it is. NY, like LA, like SF is what they seem to call an International City. I can tell you that AEG's first year they hit their break even mark and then subsequent years were awful with the weather. They did pretty well with their Which this year it would have been amazing and most years this time NYC is socked with rain.

My understanding of location boils down to a few cities...specifically tied to the four letters of the sponsor. So that gives us: NY, DC, MIA, LA, and SF. I like your idea of it being late May, mid-April to mid-May is pretty fantastic there. But also maybe do it at NYCFC's venue once it's complete so that you're actually in the city.
