There are different ways you can get to your airport, the first we would tell you is to book private Cancun Airport Private Transportation prior to Arrival since it would be less expensive and easier.
1. Priorly arranged Ground Transportation.
2. Taxis at the Cancun Airport, these taxis are a good option if you didn’t reserve any transportation prior, but they are more expensive, depending on the number of people you are it can be up to 3 times more expensive than pre-booking.
3. ADO Bus. The ADO bus departs from the Cancun Airport in two ways, one to Cancun downtown, and one to Playa del Carmen downtown, this can be a good option if you are going to someplace close to the bus terminal in downtown, but if not, you’d have to get an additional taxi and this wouldn’t be so cheap at the end. Check out more info at: ADO bus Cancun Airport.
4. Car Rental. You can rent a car prior to arrival. If you are willing to drive down in the Cancun and Riviera Maya area, this can be a good option, when pre-booking you can tell your flight info for the arrival and most of the companies will come and pick you up at the airport to take you to their office close to it.
