score:1
As it happens, I passed through the area last weekend and parked at Ferry Avenue to see for myself.
Gated parking is indeed open and free on weekends, but not obviously so. The gates are closed, but if you drive up to one, ignoring all the signs about needing a payment card, it will simply open automatically for you. Exiting is the same.
The free lots, which are not gated, are also open, but of course a little farther away.
