For those going to CC for J-Pouch surgery, you should take a walk up to the roof top Miller Pavilion. Great view of lake Erie and downtown Cleveland. Great to sit up there and watch the world from a nice perspective. I was pretty mobile after both surgeries (mainly due to the length of my time there), and it was about an 8 or 10 minutes walk at most.
The night before my reversal surgery, I stay at the Marriott Courtyard. If you like walking, take a walk to the Lakeview Cemetery. That may sound like an odd thing to do,but the grounds are beautiful. See if you can find where Rockefeller, Elliot Ness, and the guy that coined "Rock and Roll" are buried. It's just east of Little Italy.
