This is silly beyond belief. 18miles? Easily done in 6-8 hours. Sticking to the dumb managed schedule vs hanging out with the locals?! What a fool. What a dumb trade of potential experience. What story would his grandkids want to hear? “Dad spent a night with locals in a tent serendipitously” or “Dad did a Disney-fied hike by himself”.
So silly. Disgusting.
