I rented there in June. I had to check in at a booth and then picked a car from what amounted to an aisle -- i.e., a variety of shapes and sizes.
Doubt they would have started a real aisle since then, as the space in the parking deck is cramped.
Warning: be careful backing out your selected vehicle. There is a railing and some trash cans in just the right place to getcha on the fender.
