What a convoluted way to get to Cancun!
Yes, you take the ferry to Playa del Carmen, that runs every hour. Get off the ferry. go right ahead and turn right on Fifth Avenue (Quinta Avenida). Just a couple of blocks down is the bus station, with buses to Cancun leaving several times an hour. There is one that goes to the Hotel Zone (Zona Hotelera) along Boulevard Kukulcán, which passes every hotel. It's about a 40 minute drive to Cancun, so a taxi would be quite expensive.
There will be plenty of people nearby you can ask, as well as others doing exactly what you will be doing, so you just can't get lost.
Thanks for info....I know it's a 'convoluted' way to get to Cancun, but flights are quite a bit cheaper to Cozumel
