For those that dont have such as good arrangement for avoiding EWRs parking fees. The 2 best ones are IMHO, 1 EWR economy lots at $8 a day it can be a cold wait till the bus does come around and it leaves you off at the bus stands that are to the right of the term buildings and thats where they pick you up as well.
My favorite is the 4 Points Hotel at $7 a day, you ride the hotels shuttle van so you can wait in the lobby if its not there or not ready to leave. I believe it drops you off right outside the term on the departure level, to pick it up you need to get it at the tram stop for the hotels which can be a bit of a hassle if you have alot of luggage (never my case). again its been ahile since Ive done this Yrs, as I also usually get dropped and picked up by family memebers, when I couldnt be and it was short trip I parked at the 4P. id call and ask about where they pick-up/drop off to be sure.
