I'm planning our trip to Peru and it is looking like we arrive on a Tuesday morning, and the only thing that is scheduled right now is we have to be in Iquito for a Amazon Cruise the following Monday. I'm thinking Tuesday will be an acclimation day, visiting the Plaza de Armas, taking it easy, etc. Then we will have one day tour of the sacred valley, and we will spend one night at the Sanctuary Lodge at MP. That basically leaves 2 more days in Cusco if we head to Iquito on Sunday to spend a day there before the cruise (not sure if that is worth it). Is there enough to do in Cusco to fill up those 2 days, or is there something else I should be looking to do?
