Prebooked them for shuttle service from the airport to the ferry terminal to get to Isla Mujeres. Found the representative as instructed right outside the airport exit door and he contacted the driver to come pick us up. The vehicle was a really nice SUV and the driver was friendly. He made sure we knew what to do and where to go once we arrived at the ferry terminal. All our luggage was handled with care by the Discovery Mundo team. To save on any type of transportation headache I'd definitely recommend using them.
