The Beer Diaries did an episode on the Maya, with Xunantunich and Cahal Pech being the Maya sites they featured in the episode. Looks like Andy Bahadur showed them around, and schooled them on everything Maya.
"In this episode, host Mike Mann and his team visit the Maya ruins, Xunantunich and Cahal Pech, in the heart of San Ignacio. Andy Bahadur, Maya expert, explains the prominence and decline of these sites, along with the significance of the various ceremonies of the people who lived there."
