We booked our car through Costco ahead of time. I suggest you do the same (wherever you find the deal). We walked up and bypassed the long line. They offered us a nice pick of many cars (Some were National Brand). We picked a Nissan Rouge. It was brand new. It was super clean, smelled new, had every nice feature including bluetooth. It got great gas mileage without being hard to drive. Over all it was super easy. The ONLY issue is getting out. But that is something you have to deal with there because all the major renters all leave through one exit. Overall I would do it again and it was the easiest part of the trip.
