When I pick my car up at LAS, what card should I use? AMEX or VISA? I have State Farm auto. I used to use my VISA card for my past rentals, but have switched to AMEX lately. I am one of those guys that whats to make it all complete. I realize I have to turn down the insurance policy that Alamo offers me. Many years ago, I had an accident, and even though I had State Farm ins, Alamo got me for $450 because of the lost time for the car. (having it fixed), even though my insurance covered it. I was just curious about the additional coverages, which one is better.
