Our group did. What an amazing adventure that pushes someone who isn't a hiker to do what they thought they could never do. We couldn't have done it without the guidance of Paul. Extremely knowledgeable, funny, personable, all while caring for all of us. He set the expectations for each day, and at important spots would share the history.
I would call my journey to Machu Picchu as spiritual, physically and mentally challenging. And the reward ... seeing Machu Picchu ! I would do it all over again with Paul and crew. I encourage anyone to just do it if it's on your bucket list now.
