I am planning on renting a car from avis at the denver international airport in late august. I thought that if I join avisi preferred that I could bypass the lines but I was told by avis that I would still have to stop by the counter to verify my identity etc. Is there a way I can activate my avis preferred membership at my local avis branch before my trip so that I can bypass the lines? I will be travelling with small children and it will be difficult for us to wait on a long line. thanks
