Follow-up: I arrived two hours late thanks to delays at PHL. Checkout at Budget took 10+ minutes compared to 1 minute for FastBreak customers. Because I booked through Priceline my rental began and ended at the pre-agreed times, not at the actual rent time. They only had one car left in my class, a Chevy HHR. I really liked the car, whether or not I consider it a true "mid-size". Only problem was the smell of stale smoke. On the last day I found a dirty ashtray in the glovebox (it's shaped like a cup with a lid and fits in one of the cup holders). Had I not been so late I would have gone back in and asked for a different car because of the smell, but overall it was a good car.
