I just got back from Vegas and I am already planning my next trip but this time I want to drive down there. I hear from Seattle it doesn't take long and there will be two of us. My thing is I have only driven from here to San Fransisco and back and that took 14 hours, this is supposed to take about 17 hours. We want to rent a car so I am wondering how do I go about finding the best rates to rent a car and what is the best route to take? We want to go either in late summer or early fall so within the next 6 months or so, I think it's best that I start planning now so then I don't have any bumps in the road later.
