Thanks for the info. I am always worried when they have my CC info on file that they can hit me with some sort of hidden cancellation fee. I am sure I checked some boxes with some fine print that I never read when I signed up for Avis Preferred and I was worried that I had Authorized something I didn't realize I was Authorizing. I am sure eventually the rental car companies will start charging some sort of cancellation fee in the US if they are doing it overseas. Especially given how they have stuggled financially in recent years.
