Due to the great importance of Cozumel as a first-class tourist destination, it owns an appropriate sea port and airport infrastructure to welcome tourists from all over the world.
If your choice has been to fly into Cozumel, and ground transportation was not included in your vacation package, then you have to purchase it. Unfortunately, due to the Taxi Union, none of the hotels on the island are allowed to offer a shuttle from/to the airport. However, there is a 12-passenger van service available at the price of US$9.00 per person, one way.
Be aware of the fact that there are some Tourist Services Providers (Vacation Clubs) at the arrival gate, offering a complimentary ground transportation if you are willing to visit different hotel´s facilities so they can offer you a "time share".
On the other hand, if your choice has been to come by ground and see we would like to suggest the following:
If you fly into Cancun – ADO offers an A/A bus service to Playa del Carmen departing either from the domestic or international arrival gate. The ticket booth is located at the exit door of each gate. The shuttle fee is around US$8, per person, one way. Your trip will end at the Bus Terminal at Playa del Carmen's main square, just two blocks far from the ferry pier.
Once in Playa del Carmen take the ferry to Cozumel. Shuttle takes 40 minutes and it cost around US$13, per person, one way. At the exit of the Cozumel Downtown Pier there is the taxi station. Due to the short distance to Hotel Cozumel & Resort the taxi fare is around $4.00USD per cab (4 people maximum), one way.
Car Rentals are available in both Airport and Downtown Pier.
