There are many different types of long term parking at Newark. There is the long term parking which is near the monorail which is $14 a day. There is also long term parkingl ocated away from the airport, but still on airport property, a bus takes you to the terminal, it's $8 a day. We usually use a service called Avistar. They are located off the airport and VERY secure. They charge $14 a day, but if you go to their website sometimes you can get a discount coupon, and it's AWESOME!!! You drive in and the bus is waiting right there, they help you load your bags into the van for you, and then off to the terminal you go!! They drop you off right at curbside check-in(the economy $8 lot drops you off a walk from each terminal) and you're off. I've used all of the parking options at EWR and haven't had any problems, but like Avistar the best!!!
