I've searched but haven't been able to find what I was after unfortunately.

I remember reading on here about people booking the car they want, and another regular reservation in order to try and get it cheaper. Well I've done this, but just wanted to confirm that there was no cancellation fee on the reservation I didn't use?

Basically I've reserved a standard convertible (Chrysler 200 or similar STAR) at SAN, and also a mustang convertible (reserve this exact model RTAR)

I'm really after the Mustang, so if they have one available for me on the standard convertible, will there be a fee for cancelling the RTAR reservation?

Both are pay at the counter.

Many thanks chaps.
