@medic_simmons, Good morning, and Welcome to Connect. I was a 'new patient' at Mayo Rochester 9 years ago this month. Here is what I experienced: I was referred to Mayo by my local medical facility when my condition required it. I was scheduled for appointment as an outpatient. My husband and I would need to provide for our own lodging and travel arrangements and expenses. There are many lodging options in near and reasonable distance from the Clinic. And at a wide range of prices.
But, we never got to do that because I was hospitalized in critical condition locally, and needed to be transported to Mayo. So, my health situation caused a drastic change of plans and I was taken right into the hospital. In this instance, insurance took care of my costs; we took care of my husband's costs.

I believe you should factor the lodging expenses into your budget.
Here is a link to Visitor information at each of the Mayo Clinic locations. It will provide some information to get you started.

Which Mayo location are you going to be visiting?
