Step #2 Purchase your Bus tickets at the Taquilla. Currently the price is $1600 (in 2010) pesos per person, and includes transfers to other buses (ALIMENTADORES) that are located in the station where you get off. If this seems confusing get someone at the hotel where you are staying to tell you where to get on and where to get off or shange buses to get where you are going. We relied heavily on our friends, whom we affectionately call the Tomato and his wife, to explain to us how to get from point A to point B.
Step #3 You will receive a card, 1 per family with all of the money that you put on it for the trip. I the video below you will see how to use it. You can put as much money on it as you want. We put just enough for the ride there and back. That way if it gets lost, you aren't losing a fortune.
Step #4 Watch this video of how to use the card to get onto the plateform. Also remember, that if you still have moeny on the card, it will pop out. If you do not, the machine will eat your card.
#1 -- Carry your backpack on your front and not your back.
#2 -- Do not put your wallet in you back pocket.
#3 -- Don't flash around a big camera or anything expensive (no jewelry, watches, etc.)
#4 -- Be aware of your surroundings.
