If you arrive at the airport without a reservation when business travelers show up (e.g., Monday morning), this place is your only hope of getting a car. It's expensive, the selection sucks, and they try to push all sorts of extras on you, but, what can you do?
Even though they only had full-sized cars left, they were nice enough to charge me the mid-size rate when I said that my company would only cover an economy or mid-sized car, so I can't complain.
