Mexico-Holiday Ideas?

I never thought I would live to see the first day of my vacation. Since I added some free days I did not use through the year, I will have almost a month and I am really pleased I could travel wherever I want and stay there for a long time. I have been thinking about Mexico, but I need some holiday ideas, where to go there, what to see etc. Can you help?

Well, perhaps you could start with Mexico City, it is the biggest town there and you do have some time for enjoying it properly. When I was there I had to say that I was more interested in art and cultural places, even though night life is also very dynamic. I have visited National museum of Anthropology, Zocalo, Frida Kahlo museum, Xochimilco, National Palace and believe me this is just a beginning.
