Hi! We are looking into planning about a week in Arizona in late September, tentatively - we are flexible on timing and are just looking into possible itineraries. We are based in San Diego and planning on renting a car, spending a day in Phoenix, drive to Grand Canyon, spend a day, then a day or two in Monument Valley, catch a couple of days in Navajo/ Hopi country, then back home. Monument Valley really is one place that we want to see. As far as the rest of the itinerary, we are a open to suggestions of what is feasible. We like to visit cultural sites, outdoor sites and stay away from obvious tacky tourist trap areas. Appreciate thoughts on visiting Tuba City, Walpi, Window Rock and which parks are the best to visit, amount of time to spend for two forty-somethings who like to take time to explore and enjoy nature. Also, for Monument Valley, I've read that the loop road is prohibited to rental cars. I don't know too much about Monument Valley, but I am assuming that you can get to the View without taking the loop road. Yes? Also - not sure how far in advance to book rooms for this trip. We may not have the dates locked in until much closer to time. Thanks!
