We're headed to the Riviera Maya** to select a wedding venue, to that end we chose to fly in to CZM and out of CUN. What is the cheapest/fastest way to get from CZM to the ferry to Playa? (And assuming we should rent a car once we're in Playa, hopefully to be returned at CUN when we flight out?)

**We've never been and hope to cover a fair amount of ground checking out the different towns and islands.
