“I particularly wanted to let you know how highly we thought of [our guide] Juan Carlos. He is one of the best guides it has been my pleasure to travel with, having all the characteristics one could ask for on a private tour. He is personable, smart, and knowledgeable. Juan Carlos’s patience regarding the many queries we posed and the breadth and depth of his responses never ceased to amaze me. It seemed that he could talk on any subject intelligently and help us to better understand and appreciate everything we saw. He succeeded in making our time together not only interesting, but great fun as well. Please let him know much we enjoyed the time we spent with him, and that we are pondering a Teotihuacan Workout Program so we can all do the Sun Pyramid to the top and then go after the Moon, as well, on our next get together; also, that we will never forget the Chiles en Nogada meals that we savored throughout the trip thanks to his introduction to the delicacy.”
