In booking the tour, I specified the most important part would be seeing the Rivera murals at the Palacio Nacional. We did not get to enter the Palacio Nacional. We detoured to a market for the first part of our tour. That added several blocks to the walking and delayed us from sights we signed up to see. To make up for no tickets to the Palacio Nacional, at the end of our tour we continued across the Alameda to see the wonderful Sunday in the Park. That was great, but by then we were exhausted and dehydrated. The tour needs more of a story that weaves together the ruins of the Plaza Mayor with the Cathedral and Palacio Nacional with names, dates, fun facts. One of the most interesting things we learned was the story of the Virgin of Guadaloupe. More stories like that would be great. The telling needs to be loud enough for all to hear. We appreciated seeing lots of other murals in lovely buildings along the way, but as it was our first day in MX City and we are especially interested in the Diego-Frida story, his work was specifically what we wanted to see.
Mariachi men were cute and somewhat interesting - the tequila museum is a 2 min tour - oldest bar is a tourist place - wouldn't recommend.
Compared to other tours we've done with Context this was a major disappointment. Based on the description of the tour, I expected my guide to come with a full package of things we should know to tour Mexico City on our own. Instead she went to the wrong hotel and then proceeded to ask us what we wanted to see as if this were a standard tour and not an orientation tour. From that point she was basically winging it. This tour is not cheap. It was $200 for two hours. In comparison we are paying a similar amount for a 6 hour food tour with another very well regarded company and paid the same amount for a full day tour in Guadalajara. If this were my only experience with Context, I would not use them again.
