Mom’s dream of a Mexican journey

ШMy mother is 63 years old. She always dreamed see the pyramids. Once we managed to organize a trip to Egypt, but a week before our trip there began a revolution and access to the pyramids was closed. It was a big disappointment. Therefore, we dream about going to Mexico, where it is possible to enjoy the great pyramids, but also the stunning nature of Mexico.Unfortunately, the journey from Russia to Mexico is worth over 3 thousand dollars, and the mother retired, and I'm a student. So I am asking for help in the realization of the dream of my mother - to see the ancient pyramids.
