Jim,
I am sure you have thought of this already, but I would ask the club owners about parking and maybe what kind of vehicle is best- I would think they would have experience to advise you.
That location, yes it is in the heart of the Village, the streets can get very packed any day or any time of the week and NYC has lots parking restrictions and they can be different for every street. Street fairs and parades - we do have them in the fall, can add to the complications.
Also, do not underestimate NYC's ability to have a traffic jam, any time any place, so give yourself a lot of extra time.
Wish it weren't Sunday night, but I am looking forward to seeing you guys play.
