Hola Tbonita, Long time, no hear. I would put Crococun more like 8-10 minutes from the airport exit off Hwy 307. Pretty much midway between the Moon Palace and the turn off to Pto Morelos. The Playa Express drivers drive like Dale Earnhardt Jr. They may or may not let you off the bus but the speed limit drops there so they may. Another option (do it like the natives) is that there are taxis that hang out on Tulum, north of the bus station a couple of blocks, more or less in the Market 23 area. We just had a fare increase but the fares have been $45 per person all the way to Playa del Carmen. They take off when the cab has 4 paying passengers. I have been known to "buy" the whole cab for two people. They are faster than the ADO buses which are speed controlled by some hi tech satellite deal. There would be zero problem getting dropped off at Crococun. Good luck.
