I know that people are always looking for a deal on parking at Newark Airport, and there are a number of lots there that charge $8/day (which is a great deal).
I have parked at EZ-Way before and not had a problem. We pre-paid 1 day in advance. However, when my wife went to retrieve our car today, they told her that they would not honor our rate. He then treated her with absolutely no respect, and raised his voice in front of our children. I was not there, but I am beyond livid.
May I recommend ABC Parking (which is right around the corner) and charges generally around the same rates. I know I will certainly never park at EZWay again.
