This is a great tour that offers spectacular views. However, the company could improve its pick-up and drop-off process, especially given that Phoenix, Tempe, and Scottsdale are not very close to each other. Those picked up from Phoenix had the worst experience, as they had to pick up and drop off everyone else, adding nearly two extra hours to their trip. Across Arizona Tours should designate a common pick-up point to make the process more efficient. After an otherwise fantastic tour, the additional hour felt exhausting and left a bad aftertaste.
