Came into DCA on Sunday about 3PM with a res for a Full Size and got a 500. The location was jammed with cars, stacked up all over the place. I returned the car on Monday about 1PM and did not notice anything unusual. There were very few cars left but that was to be expected on a Monday afternoon. I must admit that I did not notice if there was a crowd around the booth.

I have always had very good luck at this location and have used it almost exclusively since Avis stiffed me there about a year ago. As far as customer service is concerned, I got no response and no action at all from Avis to an email and a letter.

I guess that I better be prepared because the OP has shown us that the same thing can happen with Hertz.
