Has anyone used Advatage Rent-a-Car and what are the pros and cons...there i a $60 difference between Hotwire and Advantage on a mid-size SUV......Seems like Almao--Thrifty--Dollar---Hertz are even higher.....1 week Mid size SUV $288.00 use to paying $189. Total for a full size the past four trips this year. Any suggestions would be well received.......
