After only finding Thrifty had good rates (I loathe taking a shuttle), I broke down and went to priceline, bid $15 for January 7 to January 13 for a mid-size vehicle. Got it on the first bid from Avis for a total of $153. There website is charging $291 for the same car right now. And it's on site at the airport. Just paying it forward with an FYI.
