Tulum (Cancún)

Hi, we are a Kangaroo (Australian) and Kiwi (New Zealander) living in Fiji. We are holidaying in Tulum fro 5 nights from Nov 9th-14th. We are staying at Mestizo and wondering what ex-pats recommend for us to experience when there...we like to experience local culture and experiences without the touristy touristy thing going on. We are hiring a car. Thanx for any suggestions...
