Uber is banned, the taxi mafia drove them out.

From the resort, you can have them call you a taxi. They have regular drivers they use who charge reasonable fixed fares (this is true to PDC as well). I paid 750 MXN for a ride to CUN with an excellent driver in a clean, well maintained Jetta. I'm sure they can also arrange airport pick-up and/or a more upscale ride, too.

The difficult taxi ride is PDC back to the resort. The taxi drivers will charge outrageous fares for that, i.e., 250 from Andaz, 400 back. This was a shock coming from Mexico City, where you can cross the city in an Uber Black luxury SUV for 150 MXN.
