What an excellent tour! This trip was one of the highlights of my time in Mexico. Our guide Jacqui was knowledgeable and passionate about Mayan history and the Chichen Itza. Even though the pick up was very early, it was definitely worth it as we made it to the site before all the other big tourist buses. The guide gave an invaluable information about the site and helped us to see hidden details that we would have otherwise missed. The only downside was that it would of been nice to have more free time around Chichen Itza site, as half an hour seemed very rushed, especially if you want to see the cenote which is a 5 min walk (one way) from the main area. The Ikl Kil cenote was astonishing, We spent nearly an hour swimming around it and just admiring the surroundings. It is definitely worth going into the cenote first and then going for the buffet lunch. Just a minor thing-the van didn't have much leg room and some seats were broken. Would of been nice to have a better transportation.
