John, good move changing the route from 4-corners to Monument Valley (Hi 163). I've done both many times and Hi. 163 is far superior. Great views of Monument Valley, you'll drive through Forrest Gump Point, and the colors in Raplee Ridge around Mexican Hat are fantastic. Be sure to do the 3-mile side-trip to the Goosenecks. If you have an hour to kill, also run up and down the Moki Dugway, a classic photo op of the Desert Southwest.Got all the bookings done, planning a circuitous route around with RONs in Winslow, Moab, Page, and Prescott. Stops along the way as they happen, but Monument Valley, Lake Powell, and Hassayampa River Preserve are along our route so kinda already in the mix. We'll hit others as time & interest permit.
