We are planning a trip in May. We are flying in and out of San Francisco. Our initial idea was to go first to Yosemite and from there go to Monument Valley, via Hurricane and Willams, and then on to Vegas. After Vegas it is LA and then back up the coastal highway back to San Fran. Having done some research the route looks OK except the trip between Yosemite and Monument Valley looks pretty long with not much in between. Any advice on if this is a good idea or any alternative route would be most welcome.
