The journey from your cruise destination, Cozumel, to your desired location, Playa del Carmen, is thankfully, pretty seamless. The ferry terminal on Cozumel is in the downtown area so getting there will depend on where your cruise ship is based. Unless you're docked at Punta Langosta, you'll need to grab a taxi down to the ferry. You'll be on the ferry for roughly 45 minutes before arriving at Playa del Carmen. Although, Ultramar has added some super modern boats to their fleet which drastically decreases travel time by 25 minutes!
