When we went on the Conquest this past year, we were in Cozamel, Mexico, there was a couple of people that ran late. We heard them calling their names out on the intercom and later when we were out on our balcony's we saw them being escorted onto the ship. I don't know if the cruise people went to find them or what but they made it back on the ship. I also heard (through the grapevine) that a couple of young adults were in a bar and lost track of time and missed the boat. I heard they had to rent a car and travel across the island to meet the boat again. I don't know for sure on any of these but my suggestion is.....be on time. I wouldn't want to find out for sure myself....lol.
