Willowbrook Park and Ride help! What do I do if monthly parking is full?

Hello! I’m about to start commuting into Port Authority for work and have purchased a monthly parking pass for the Willowbrook Park and Ride.

When I tested this the other day around noonish (which will be my job start time) there were barely any monthly parking spaces (green spot with white numbers).

If they are all taken, where do I park? The daily parking spots or just a regular white spot? I don’t want to get towed of course. Anyone have any advice?
