Joanne, I know hotel stays can be pricey. I’ve had to stay at a hotel for a total of over 6 months in my cancer journey. But I’m so grateful for the opportunity to be at one of the most highly regarded medical facilities in the world. The money I spent was well worth it. Without the care I received at the clinic I wouldn’t be alive today. So it becomes a matter of perspective. Remember, it is the rates the hotels are charging, not the clinic.

Talk to your insurance carrier, often lodging-some or all of it can be covered for a serious illness.
If you do need to return for further treatments, speak to someone in the hospital’s Social Services department. They will be able to provide various options for stays and can take into account your financial status to find affordable lodging.

You might try looking few miles away from the clinic for lodging. Hotels will definitely charge more the closer you are to Mayo. (Or any sought after destination). The further away, the prices would be less expensive and most hotels offer shuttle services so you don’t have to drive and find parking.

Here are few links which might help you in planning your trip.

Have you tried looking a bit further away from the clinic?

I understand the cost can be frustrating. I had to fly to Rochester because Jacksonville could not do my surgery. So I do get it, most of us understand. Many times Mayo only sees the most complicated cases, so we all have had to go through expenses of care. It’s doesn’t seems fair but like @loribmt stated Mayo has saved our lives, like her I may not be here without them. I do now live in Jacksonville, as I recently moved there. There are a number of hotels within a short driving distance to the campus. When I was traveling here, because all my follow up care is done here in Jacksonville, I would drive here frequently, I would always stay a mile or so away and drive over, it was cheaper. There is free parking available at Mayo if you park outside the parking garage, and a shuttle to pick you up and take to the other buildings if needed. I would check with Mayo like suggested, for my initial appointments I received
All my information in the mail with my Mayo number and instructions on setting up my patient portal. After initial appointment everything just went straight to the portal. I have actually been to the Jacksonville campus 4 times over the last month and am returning Monday for more tests- it is very efficiently run and organized. Please call as suggested- and understand with Covid the system was just stretched beyond its limits and is finally recovering. Best wishes!

You can get an Airbnb which will be cheaper than hotel. If you need help let me know

There are many possibilities to stay for less money when at the Mayo. I was the last week for surgery, and had to stay for the preop, and post op visits. My adult daughter was with me, and I rented an Air Bn'B apartment. We had two bedrooms, a bathroom, a kitchen and a living area, and it was $60 per night. It was about 30 minutes car drive away from the Mayo.
