@baker001, Have you seen the Mayo Clinic Florida Buildings & Maps page? -- https://www.mayoclinic.org/patient-visitor-guide/florida/campus-buildings-maps

Depending on which building(s) where you have your appointments, the maps might be helpful and the cafeterias could be a place to rest between appointments. There are normally some comfortable chairs or benches located throughout the different buildings, at least there are a lot of them in the Rochester facility.
