For everyone's info..I ended up using an outfit called "Park 2 Go" which is on Dowd Ave. in Elizabeth.

It is also $9/day for stays of 10 days or 14+ days ($10/day, but if you stay 10 days you get 1 day free, and if you stay over 2 weeks you get 10% off your entire stay).

They were very prompt both dropping me off (admittely, I arrived in the middle of the night, so I was the only customer) and picking me up (the shuttle arrived within 10 minutes of my call).

I would use them again.
