Downtown Cancun Bus to Chichen Itza?
 

We understand that you can catch a direct bus from downtown Cancun to Chichen Itza. We are staying at the Westin Cancun at the far end of the Hotelera Zona. How much does the direct bus cost to Chichen Itza? Can we just catch the bus outside the hotel and get to the bus station?

How long should we plan on the trip taking and what time does the last bus leave Chichen Itza to return to Cancun?

I know lots of questions here!
