We plan to try both in Feburary. Fly into Cancun, spent 4 nights in PDC then take the Ferry over to Cozumel (about $12 one way) and spent 3 nights there.Flight back to Cancun via Maya Air($58 one way). Rental car for one day in PDC to drive down to Tulum and one day in CZM for a trip around the island. I have been to CZM many times for diving and love it , been through PDC but have never spent much time there. Both locations are very safe, looking forward to seeing more of the PDC area. <img src="http://www.traveltalkonline.com/forums/images/graemlins/Grin.gif" alt="" />
