Saturday afternoon - the shuttle bus driver said they had rented 1200 cars between Thu/Fri and National/Alamo. Given the tiny lot they're using, that's amazing.
The EA had basically nothing on it, one sedan that looked like a midsize. The ES had about 10 vehicles, all domestic SUVs/Crossovers. Suburbans, Escapes, Journeys, and GC Laredos. I took one of the Laredos as they are just a little bigger than the Journeys and Escapes and not huge like the Suburbans. They seem to be the workhorse of the 2011 National SUV fleet, and I don't mind them.
The Laredo I selected wasn't as well appointed as some of the others I have had, cloth seats instead of leather, and the push-button ignition was missing and instead required a key. But it only had 11k on it (and NY plates) and working Sirius. Also, it had the ES box checked off, and it's right in view of the gate agent, so no sneaking an ES car with an EA reservation here.
