Good evening @hkjp. I don't know about all the hotels within walking distance of the Mayo Gonda building. We always stay at the one that connects to the Mayo through the underground walkways. They have special prices for Mayo patients. And the prices are dependent upon the size of the bed and the location of the room. I also don't know if the prices are seasonal. It might be worth a phone call or an online connection to find out.

May you have peace and contentment.
Chris
