I would like to add my two cents and say congratulations on choosing Mayo. We stayed at the economy version, called extended stay the first time we were there for 4 months. It was clean and comfortable but without the extra space and amenities. We still had a shuttle to Mayo almost every hour if we chose to use it, and a little kitchen for fixing food.
The second time we had a little more time to prepare financially and we stayed at Townplace suites for 6 months. This was a one bedroom, but the bedroom had a door, so one could rest and one could be awake. It also had a much better equipped kitchen. Mayo shuttle connects you to the clinic every hour during the day. Be sure to ask your driver for advice if you need it, relating to Rochester, they live there and drive patients all day long who often are in need of the very same things. If you stay in one of the hotels down close to the clinic there are winding subway and skyway tunnels that will get you there without even going out in the weather.
This is all secondary to the instant feeling of awe and calm when you first enter the Gonda building ( main clinic building). They will give you an agenda which could change but they print you new pages if it does. They will run all the tests they need to acquire the best information, the doctor you see will actually read those tests and answer all your questions and help you decide what is the best course of action for you.
I enjoyed the sense of knowing we were in good hands and feeling the first hope that my husband might have more than a few months left with me. Thankfully, we just passed 11 years since his diagnosis.
