hi , can anyone help me.Will be in vegas for two weeks end of august.I am from uk .Part of my holiday is free car hire.Has anyone any idea how much full insurance i would have to pay at desk. It is with Dollar. I got a quote from my holiday company for approx 400 dollars. If i book at Dollar desk when i get there would this be significantly less. thank you for taking time to read this, any help at all would be gratefully received tytyty.
