I asked our hotel clerk - tell me about walking here in Scotland. He looked puzzled. I clarified - you drive on the left... “Oh! he says, yeah, there are no rules. It’s a madhouse. Everyone for themselves.” If you don’t mind the rugby scrum of narrow pavement (sidewalks) with thousands of tourons (tourists + morons) then maybe you’ll enjoy the Royal Mile. The old architecture IS interesting, just too many people for my taste.
