Have used Winner many times for PHL parking. Great service! Look for coupon. With kids, gear and luggage this white glove service is awesome! You drive to their lot. They drive you in your car (and you kids, car seats, gear and suitcase) and drop you off at curbside check-in. When you return, call when you have your lugggage. They meet you in your car and help you load it up (allowing you to get your kids situated). You can either have them drive you back to their lot to settle the bill and drop off driver, or for a small fee (10-12$) you can just take your car and leave and the driver will get another ride back. Well worth it, as we usually get back late and have an 1 1/2 hour drive home. Highly recommend!!
We are flying out of Newark this trip and I am beside myself not having a service like this at EWR.
