We're trying to decide what to do in the last 3 days we have left of our trip to Peru. We would be leaving from our last destination, Cusco. We need to end up in Lima since our flight home leaves from there so we'd like to at least have the last day there. We're undecided if to fly from Cusco to Arequipa and spend that day we get there and the next visit Colca Canyon OR just fly back to Lima, rent a car and drive down to Nasca to fly over the nasca lines hopefully that same day. Any recommendations? We're a group of six. Thanks!
