Queens night market, behind the NEW YORK HALL OF SCIENCE Flushing Meadows Corona Park, Queens sneak peek

Apparently it has been well attended. In an effort to control crowds, this year they are offering 2 sneak peeks that will require purchasing tickets $5.00 per ticket.
Has anyone been, it worth a visit and if so exactly how well attended was it, were the crowds a deal killer … TIA ?
