Gil - NJ
I've used this service for a couple of years now, about once a month I park for several days. Three big advantages - 1. very very close to the airport. 2. the shuttle always arrives within 10 minutes of calling. And when leaving for the airport - there is always a shuttle there waiting just for you. 3. Lowest price.
Though one time it took them 45 minutes to locate my car, that was the exception. Overall a positive consistent experience.
