Our trip was tremendously involved & kudos to Ivana for putting it all together & organizing so many moving parts. Every tour she suggested that I wasn't sure I wanted (such as food tour in Mex City & indigenous peoples tour near San Cristobal) was really fun or amazing or both! Ivana knows her stuff!! We were thrilled with the itinerary she put together because it kept us on track & some of the little added hints (about taxi costs, reasons for departure timing, etc) really helped us plan. Also, of all the guides we had, we especially liked Dante in Mex City who took us to Coyacan (22-Oct), Cuernavaca/Xochicalco (23-Oct) and Teotihuacan (25-Oct); he was very well versed with details of history & art; he negotiated through a lot of traffic very calmly & he was fun to talk with during lunch stops or while driving. We would definitely recommend both Ivana, Dante; all the other guides we had were also good but some were more abrupt or late in arriving.
