My wife and I recently used Discovery Mundo for round trip airport transfers in Cancun. Our driver was waiting for us outside baggage claim when we arrived, and he could not have been more courteous or accommodating. For the return trip, our driver showed up five minutes early, and got us back to the airport without any challenges. Overall... we were incredibly pleased, the service was perfect, and the personnel very gracious. I have no reservations recommending Discovery Mundo to everyone here.
