Will be in the Sacred Valley from May 4-7, going to Aguas Callentes from 5/7-8 and then Cusco from 5/8-10. What are the prices range for guides/ tours? Is this something we can arrange once we arrive? Will be staying at Tambo del Inka in Urubama, El MaPi in Aguas Callentes and Novotel in Cusco. Suggestions on guides/ tour operators greatly appreciated.
