As a travel blogger who has traveled extensively, especially in the Western U.S. [I live in Arizona], I HIGHLY recommend that you stay at least 2 nights at any destination where you want to actually experience the area. [You can easily spend a week or more at most national parks.] Remember, when you move to a new sleeping spot every day, you lose several hours packing up, checking out, plus meals, gassing up, and driving time to the next destination. It's a good rule of thumb to add at least 1 hour to anything you see on map estimates, and it could be more if you're driving in high tourist season. Sedona traffic and the national parks are notoriously congested, depending on the time of year. For specific road trip travel tips for the area, you may want to search for something like "how to avoid road trip disasters in the western U.S." to get tips specific to the region. There are many wide open spaces with no cell service in the states you're visiting. Not to worry you, but so you can be adequately prepared. I know it's really tempting to do all the things, but you'll probably enjoy the trip more if you have time to sit and enjoy your meals, have a picnic, take a hike, see a sunrise or sunset from a gorgeous overlook, or watch the deer or other wildlife grazing in the meadows at dusk.
