If you search for Tucson Airport transportation and Tucson Airport Shuttle comes up, do not use it! I made a reservation with them for transportation from the Tucson airport to Green Valley. In the SLC airport, I ran into a friend who was going from the Tucson airport to Green Valley so I called and cancelled my reservation with Tucson Airport Shuttle. I was told my credit card would be credited($ 52), but a month later it has not been credited. I’ve called the Tucson Airport Shuttle office numerous times and have been either hung up on or told to call back later. Very frustrating!
