If you choose to rent a car, here are some recommendations:

  • Self-parking is complimentary at the hotel – Upon arrival, visit the front desk first to get a ticket to enter and exit the parking garage. It is recommended to leave your luggage at the bell desk at this time since the parking garage is a decent distance from the guest rooms.
  • There are many options within and near the Tucson International Airport that can be found here.
  • It is advised to make rental car arrangements early as the rental companies often run out of cars during this season.

If you choose not to rent a car, the resort does offer a local shuttle for $35. Call them for more information. Utilizing private rental services like Uber and Lyft is also an option.
