Honestly nothing. It took nearly two hours to get the car. The line was incredibly slow and a total mess. We had reserved an Audi, but they only had a Ford Focus, and tried to claim it was in the same class. Then they tried to up sell us. They were doing the same thing to everyone.
The pick up process was a total mess. They are very deceptive in the classes of car that they advertise. It took about two hours to actually get a car. Would never rent from this Avis again. Allow yourself time for the return as that also takes longer than it should.
