I will try my best to help. If you are talking about the small bus stop on RT 9 outside the Shoppes at Old Bridge, then I do know some details. My wife usually commutes from the bus terminus in Old Bridge Township. We live in Morganville and find it easy to just drive to the main stop at Old bridge and commute into the Port Authority from there. You willprobably have a better chance in finding a spot as well. Non residents of Old Bridge townshi can apply at Park America which runs the commuter lot for a permit. The trip into the city is about 1hr. Fairly trouble free.
The cost is about 8.50? from Old bridge. expect to pay about 10 -12 bucks if you are coming from Rt 9 and Texas road. If you are a marlboro/morganville resident..there is a commuter lot next to the Regal Cinemas and I HOP across the way from the shoppes at Old Bridge. Other than that there are no other parking options. The mall doesnt allow commuter parking. Theere is a bus stop outside the I HOP. the bus that goes into the Port Athourity should be #139. The time would be about 1hr and 20 minutes give or take.
