I was nervous using the shuttle for the first time but they made everything easy and smooth. They arrived 10 minutes early and had everything set for all passengers. The driver (Ute?) was sweet and polite and knew what she was doing! We departed right on time with everyone in the [comfortable, but not full] van. We had a stop half way from Flagstaff to Phoenix and got to the airport earlier than planned! Highly recommend!
PS. I did not interact with their customer service (which everyone seems to think is bad) but the driver really was great!
