This shuttle is much more expensive than the alternative for going from Tucson to Phoenix. The employees area also extremely unfriendly-- if you have an issue their preference is to turn you away and offer you a refund. In Tucson, the parking is also a huge issue. They advertise free parking at their Speedway and Ina locations, but in reality there are never spots. When you book your trip months in advance, planning on parking your car there, it is extremely inconvenient when they threaten to tow you for parking. I will never use this shuttle. If you have someone to drop you off, it might suite your needs, but if you plan on using the free parking, don't fall for the trap!
