If your going to cancun you must take this trip. A great day out. Chichen Itsa is an amazing place and the stop at the cenote caves was fabulous.
I was very lucky to have the tour guide Rubens. Rubens was so helpful and gave you all info on the ruins and mayen culture. He also acted as translater for you if you needed help with the language while trying to make any purchases.
Go on the Chichen Itsa tour , its worth every cent. And even better if your guide is Rubens.
