Our first trip to Playa we were going to stay at the Porto Real, only to get bumped to the Cameleon Maravel in Puerto Adventures. 2 days later we booked a snorkel trip thru the hotel for Cozumel. They picked us up at the hotel along with a dozen or so other people and off we were to the ferry.
When we arrived in Cozumel we boarded an old wooded pirate type of boat and headed for the reefs. After we stopped for lunch, our crew informed us that there was no power on the boat and had taxis lined up outside the restaurant to get us back to the ferry.
Well after missing the ferry and waiting an hour for the next one, we were wet, tired, and cold, heading back to Playa. Reaching the pier we were excorted back to a bus in the dark. Then waiting for our driver, he announced that the head lights weren't working and he would have to find another bus.
I think it was around 8 or 9:00 when we finally got back to our resort.
Tired, wet, hungry, and laughing at everything that went wrong that day.
We still laugh about it 5 years later.
