Ah yes, the Maya did not have the tradition like the inca to bury 100 human and lamita babies alive on solstice. And I am not an expert in the various rites of human sacrifice. But what I understand is, that a sacrifice is more powerful, if the sacrifice is more valuable.

So if this was the norm:

"Some other sacrifice related practices include burning victims alive, dancing in the skin of a skinned victim, taking head trophies, cannibalism, drinking a deceased relative's bathwater, and sprinkling sacrificial blood around sanctuaries"

then the only reason for them to not sacrifice babies regulary (but I am pretty sure they did so on occasion, too) would be, if they would not deem them worthy enough. So my point kind of still stands: why would you want to visit such folks?
