I am trying to make arrangements for my daughter and her bf to meet me in Palenque the week of 12/17 for the end of the world. I am just starting my research into this. Anyone know if there is 1st Class bus service between Mex City and Palenque? Air Service from Mex City to Hermosillo and then bus to Palenque. I have a lot of groundwork to do and was hoping that one of you out there could give me some leads.
