We are a family volunteering in Cusco for a week in July 2013. My plan was to fly into Cusco a few days before to get acclimated. We can visit Machu Picchu either during our volunteer week or after. Then I'm not sure if we should stay in Cusco and fly home from there, or go somewhere else for a few days. We can't afford to spend much. Any help would be great. Thanks.
