If you are staying in the Hotel Zone in Cancun, this is a convenient mode of local transportation. I found it hard to find information about this, and I was initially nervous about getting lost and wasting time. But for our trip to the mayan museum and the El Rey ruins, it was perfect. The buses run frequently....We hardly had to wait at all. The drivers, though their English was limited, were friendly and helpful. Just tell them where you want to go, and they take you there. I also used Google maps to keep an eye on my destination. We paid $1 per person for each trip. One of the drivers gave us a bus map, which I am posting here. As well, visit their website for more information. http://www.autocarcancun.com/Qs read more
