Okay, stupid question, but where is the employee parking lot at Newark, and are there any parking permits or anything like that we need to get beforehand?
Yes, you need to fill out a form in the parking office in Terminal C - you can register two cars. They will give you a map to get to F lot which is at the end of the runways on the south side - very convenient to get on the turnpike going south.
South street lot has a waiting list.
You then need to go to the office at the parking lot where they will give you a pass
