There will be companies that will try to sell you private transportation directly to the city of Tulum. However, they are noticeably more expensive than bus transportation, but you are always free to make the decision that seems best to you.
This is the main Bus Company in Central and South of Mexico and our best recommendation to get to Tulum and then the Course Venue.
Note: These buses take off and arrive at/from the bus stations without any intermediate stops (like public transportation does).
You can purchase your tickets directly in the counter of the Bus Stations or Airport Desk or you can do it online here: https://www.ado.com.mx/
Those are the common routes you might use during your stay:
Make sure you purchase your ride to Tulum Downtown/Bus Station and not to the Tulum Mayan Ruins Site, from the Ruins there is no shuttle and it is harder to get public transport or a cab than from Tulum Downtown.
If there are no rides to Tulum upon arrival, you can move halfway if you take the bus to Playa del Carmen and then, from the Bus Station buy a ticket to Tulum as they run with high frequency, also you can take a Van (public transportation).
This route runs the latest from the airport, so if you didn´t catch the one to Tulum or Playa, you can take this and from Cancun Bus Station you can take a local route as they are more frequent.
Also, if you are staying in Cancun before the course, it is easier and much cheaper to take a taxi or an uber from the downtown area than from the airport.
This is the adventurous option and consists of two types of vehicles: Van & Sprinter.
The Playa Express Sprinters are owned by ADO and you can take them in the parking lot of the Bus station, their one and only route is Cancun - Playa - Cancun.
The Vans are located in Cancun at the Soriana Supermarket across the street in front of the Main Bus Station and in Playa del Carmen at the 50 Avenida Norte corner. 1 Sur.
You can rent a car directly at the airport or in Cancun / Playa del Carmen (downtown). Take Federal Highway 307 towards Tulum (heading south). Passing kilometer 232, between Akumal and Tulum, there is a return. Make a U-turn and after about 700 meters, on the right side, there is the entrance to Caleta Tankah.
