We’re excited to be heading on our Hidden Galapagos and Peru trip in a few days. We received our Tauck duffel bags for the night in Machu Picchu. I understand our big suitcases go to Cusco ahead of us. Do we bring our usual carry on case with us and the duffel for that night or only the duffel? Also, any thoughts on which excursion you liked for the day in Cusco? We have a choice of a highlands visit or a city tour. Both sound nice.
