Yes! This is the one. I'm also a member. There was the Chili pepper festival this past weekend and the parking was a flat $18 fee(!) too much for just a charging session. BUT if I had brought a parking pass it would have been free.
Re: BBG/BK Museum
The superchargers in the lot for Brooklyn Botanical Garden & Brooklyn Museum were very quiet when I used them Sunday.
I did notice a few of the chargers were still being installed and not operational yet.
Also gives you front row parking relative to the Botanical Garden. It's a self park lot and would have been something like $6 had I had to pay.
William Vale is still closer to me, but the more the merrier.
