We will be in Mexico City for 5 touring days before Christmas. We were thinking about using guides for 3 days, but were hoping we could see the most important museums on our own. What is the experience for English speaking tourists? Are their audio-guides in English? While the Anthropology Museum/Castle are a must, we want to go to a few other worthwhile museums. Suggestions would be appreciated. Many thanks for those of you who take the time to respond.
