Actually, there are 2. I got a tour, but was utterly lost my first time. The tour was Tuesday, 5:45. The big pool had at least 3 people per lane, which I thought was crowded and the tour guide said it was "busy".
The next night, I went and shared a lane, circle swimming, with 3 other people. It felt giant compared to Greenpoint.
And not crowded at all!!
