Well if you really are interested in Mayan history the best sites are Palenque (MX) and Tikal (Guatemala). Given your specs I'd opt for the bus to Chitzen Itsa. We've done it several times ....early ferry to PDC, bus to CI, bus back to PDC and dinner there and a later ferry back to Coz in time for a night cap margarita at Wet Wendy's
It's a solid day!
