Xcaret at Night starts at the main entrance with a tour of the reproduction Mayan Village in your choice of a half dozen languages. You walk through a candle lit cave and see an enactment of a Mayan ceremony in the village. Afterwards, everyone goes into the theater for a folkloric show. Currently, the show features music and dance from each of Mexico's states. The restaurants are a little expensive, but the Mexican Restaurant by the horse stables serves good food and in the afternoon you can watch the horse show from your table.
Horse rides are extra, of course.
