I am heading out to Vegas in October and with the rise in rental car prices I am wondering if its possible to do both in a day. It will likely be the first day arriving in Vegas from the east coast so I will more than likely be up and ready to go by 6am. I see its 25 minutes to Red Rock from the strip and about an hour to Valley of fire from the strip. Im not planning to do a long hike at either probably just go do a short 30-60 minute hike and then leave. Do you think this is possible? Would you plan to spend more time at one than the other?
