See Wik Chichen Itza ("This long-held chronology, however, has been drastically revised in recent years. As archaeologists improve their knowledge of changes in regional ceramics, and more radiocarbon dates arise out of ongoing work at Chichen Itza, the end of this Maya capital is now being pushed back over 200 years. Archaeological data now indicates that Chichen Itza fell by around AD 1000.[7- E. Willys Andrews] This leaves an enigmatic gap between the fall of Chichen Itza and its successor, Mayapan. Ongoing research at the site of Mayapan may help resolve this chronological conundrum.")
This places the whole story of HC into a problematical light.
