Is this just a sneaky way for them to charge my credit card if I don't show up for my reservation? Since my CC is in their system if I don't show up, I am assuming they are going to start charging my card automatically. Has anyone had any experience with this. The reason I ask is I will be renting at KOA and Avis has the best rate but I have heard bad things about Avis at this location. I signed up for Preferred, but then I have read that they still make you come inside anyway at this station. I have a backup reservation with Enterprise, no CC required, if AVIS is totally out to lunch, but now I am thinking they will charge my card if I blow them off.
