OMG....just avoid this place!  Not only are they not on the airport site, you have to take a shuttle to the airport then another shuttle to this place.  Cheaper than most rental places, but besides the shuttle, and then waiting in a horrible long line, they give you a rental car that has alot of miles on it.  Mine had about 60k.  \n\nTHEN, one of the tires had a slow leak.  They said I should have exchanged it for another car right away, but this place was across town from where I was staying and had a conference I had to get to all the days I was there.  I had no time to drive across town to wait in another long line and exchange it.  So I had to go to the gas stations 2 times a day to fill up the tire that was leaking.  \n\nThen they would give me more than a day free.
