Parking across the street at the lot is only $7 a day.........can't beat that! Great for leaving your car there instead taking the $8 Holland Tunnel and trying to park in NYC!
If you are going to an event at the Red Bulls Arena, buy your 2-Trip PATH MetroCard or add sufficient funds to your SmartLink Card or Pay-Per-Ride MetroCard, to avoid lines on your way back.
