I used Alamo at the beginning of May. I had booked a mid-size and they did not have any. They offered either a mid-size SUV or standard car. There was plenty to choose from though definately not as stocked as Terminals A & B. It was very easy to negotiate getting in and out of Terminal C (way less traffic and congestion). Although Alamo employees were still learning the "lay of the land" in Terminal C, the service was great. After some of the car rental experiences shared on here, I am sticking with Alamo.
