Flew in here last night. As stated above, National and Alamo share a counter. Inventory appears to be half shared. There was a National-only section, an Alamo-only section, and a National-Alamo shared section. No line when I got there, and the agent was very quick (already had all my info).

Despite being executive I was offered a standard Impala, Camry, Altima, or Maxima. I ended up taking the Maxima, had about 10k miles but otherwise a nice car.

The car lot is just outside the door from baggage claim. I didn't look too closely, but was a solid collection of cars in the Naitonal section (Caddy XTS, some jeeps, challenger, and some other things that would normally be in the executive isle.
