Good morning! A few month I will go in Cancun!!! I would you like visit Chichen Itza. There is a bus from Cancun alternatively a ADO? I find a bus which start 8 o' clock and retourn in Cancun 16 o' clock about! Bus colectivos? Thank you Laura
I think from the website the ADO leaves at 9am and takes 3 hours - then returns at 16.30 http://www.ado.com.mx/ Giving you about 3 hours at Chichen Itza. I would recommend the tours though the guides are great.
You should check the Entertainment Plus link at the bottom of this page. They have different options for going to Chichen Itza.
Fully agree, for the price get a tour, as you get to see a few other bits and bobs too, plus the food, guide ect ect.
