I found good deals of car rental in UR for my upcoming Denver trip. What's even better is that my friend (travelling with me) has a CSR, which makes 1.5 cents for each point! My question is can we book the rental under my name, using my friend's UR account since I am the one driving. I am aware this would lose the primary insurance provided by CSR. But I think cost wise, this is the best option. Is this doable?
