Early this year, New York governor Andrew Cuomo announced plans for the construction of the nation’s biggest convention center (plus casino/hotel) in the NYC borough of Queens…to make New York a raging hub of convention tourism and help it grab a larger slice of the $907 billion American-meetings-industry pie.

But data from the last decade indicate that large conventions are on the wane. Also, many trade-show organizers insist they will take their shows out of New York before going to Queens.
