I've watched the ferry come over from Cozumel to Playa del Carmen. You need to keep an eye on the schedule so you don't miss your ship. I've seen people running to the dock trying to catch it. Its right next to Senor Frogs and all of the shopping so you don't have far to go. The beach is also right next to it.
Life is too short to let the ship of your dreams sail without you.
