My mother has done it, but it was a "light" version, not the whole thing. I have a few friends who have done all the way, and others who have done it by bicycle. It's a very pretty trip, and for the more religious ones, supposedly very enlightening.
My wife's doing this in May next year, not the whole thing though. Her and her sister doing around 10 days, they can't wait.
