We can help you out, through our Property Manager, to get transportation from and to the airport. Eventhough you do not need to rent a car, as taxi and other private transportation options are available, doing so opens up a lot of options. The Cancun-Tulum area is not only quite large (more than 80 miles/130 kilometers), but it is a corridor full of fun things to do, that go from beautiful beaches, aquatic parks (Xcaret, Xel-Ha), ruins (Tulum, or going towards Merida you have Chichen Itza at about 2 hours from the condo), and many, many other options. So, no car needed, but you will have an easier access to the above options (and more) if you do so.
