Gym or swimming resources?

Hello!
My husband and I are headed to Mayo today for many tests and surgery. I have been doing PT in preparation for my surgery and will have a week there prior to the surgery. I am advised to continue this, if at all possible. I contacted the Abraham Center for Healthy Living, but they serve only Mayo employees. We will be staying at the Marriott Residence Inn (gym, but no pool). Is anyone aware of a pool resource I might be able to access while there? Another Marriott property that might allow me to come for that? (will check with the manager when we arrive at the residence inn). Thank you so much!
