I have just returned from 2 weeks in the US where we used 3 different car rental agencys. Each of them required the credit card and drivers license to be in the same name. My credit card expired while I was away (grr!) and as I was the designated driver for the trip we faced issues every time even though we were paying cash for the rental! I ended up having to get my friend to rent the car using her license and credit card, paying $25 extra a day as she is under 25 (even though she was never once going to drive), and an additional $10 to add me as a driver! When you add on tax and insurance etc teh overall cost was pretty ridiculous.
