Show up with a plan and the walk along the Asi rewrites it completely — nobody minds. Getting lost in the narrow streets isn't a slip-up here, it's basically the itinerary. Sit down for breakfast and somehow it's noon and you're still at the same table. In the old bazaar, "let me just take a look" swallows two hours whole. Leave the hurrying to some other city. Sit down, roll the dice, and let the rest flow on its own.
