When we were there Oct 27th-Nov 4th, Alamo had only three Premiums in the lot. One was a Mitsubishi Galant, one was a Nissan Maxima, and I forgot what the other was (a Ford maybe?). We took the Galant, because the other two had quite a few scratches and dents. This was about 2:00pm on a Saturday afternoon. We weren't thrilled with only three choices, when two of them were pretty beat up. However, I guess I got lucky, because I posted the exact same question you did and also did a search here on the DIS about Premium cars and found one post where there was only one Premium car on the lot when a DISer got there and then another where there was only two to choose from. I booked a midsize the month before (Sept) and had a bunch of cars to choose from, so was disappointed with so few Premium cars.
