How much does it cost to park on Sunday at the Port Authority on Sunday?

no idea, but parking in NYC is very expensive $$$$

Parking in garages is expensive.Parking alot further from the portauthority on the side streets is best.

Sorry I didn't about parking I taken the bus from hackensack nj. It cost me 4 dollars and fifty cents one way

I'm not sure of the price but expensive.

Try parking at hotels or side streets it gets pretty crowded anyway

Public parking is not an issue but garage parking is sometimes expensive on the weekend
