There is an arrangement with Mayo for patients of the hospital, but not specifically with the ACS.
Check the Mayo Arizona web site for accommodation recommendations. Small discount at the Marriott similar to that for Marriott rewards members. More substantial discount for extended stays. The Village at Mayo Clinic offers low cost lodging for cancer patients, but I don't qualify and haven't stayed there.
No for Mayo patients/family, but I didn't check with ACS. Might be worth checking out.
