Just checked in yesterday, and it is pretty much on the honor system (or so it seemed). The CM asked me if I had a car, and I said I was only renting one for part of the time. I said Wed. - Sun., returning the car on Monday morning. He charged me for only four nights (?) I asked again, and he insisted on four, so I let it go. On our keycards it says "self-parking". I guess that is how you get through the gate.
