Luckily for us, the day started out with sunshine instead of rain. We rode on the top, outside area of the ferry for our crossover to Playa del Carmen. A guide picked us up in a van at the ferry dock. He drove us to a shopping mall where we checked in with several tour groups. They were very organized and separated people onto buses according to which resort/area they were staying. This made it faster for drop-offs at the end of the day.
We made it back to Playa del Carmen in time to catch the 10 p.m. ferry to Cozumel. It was a long exhausting day, but well worth it.
