You have a few options to get to your vacation rental in Cancún from the airport. The most expensive is the airport taxi, and the charge is based on the distance to your location, this is a good option though if you are traveling in a group of three or more. There are also shared shuttle buses which are economical but charge per person, however, these will only go to hotels, so you may need to give a hotel closest to your vacation rental. Alternatively, there are private transfers available too. You can also take a local bus to Cancún and take you to the bus station in downtown Cancún.
