Booked ahead of time and printed out pass to put in my car. There was no one at the front desk when I arrived (at 4:45am so that may be why), and I had to leave to catch my flight before someone arrived at the desk, but I just put the printout on my windshield and had no problems. The airport is a 5 minute drive from the parking and they offer a free shuttle service. When I landed after my trip, I called them and they sent someone to pick me up. Very easy to use and very convenient. Will likely use again!
