We booked the trip through a company that provides transportation to and from the ruins and a sink hole, plus adult beverages and food on the coach bus. We traveled with about 50 other people and our amazing tour guide Reyes aka Rexy aka Sexy Rexy back in time. He gave us an in-depth look into the Mayan culture and admitted that archeologists haven't figured out everything yet. So much of this ancient culture was based on the Milky Way Galaxy, our twin galaxy, mathematics, spirals, and much more that was very advanced for their time. Without the historical context, just walking around Chichen Itza would have been super lame. If you enjoy history, and a lot of merchants trying to sell you trinkets, Chichen Itza is for you.
