From a passenger: We were on the Carnival Dream sailing 08/07 to 08/14 and heard that a brawl broke out in the dance club around 3:00 a.m. on the morning of the 12th. We heard from passengers and a bartender that the brawl started over a song. It involved so many young people (men and women) that the security on board was unable to handle everyone and had to call in assistance from wait staff and other crew members. The fight spilled over into the art gallery located next door and apparently a $10K painting was ruined with blood spatter. Flat screen tvs were smashed and there was a lot of damage done. We heard that people on the ground were getting kicked in the head by men and women and that one person needed to be revived because he was hurt so badly. We also heard that the crowd spilled out of the dance club and that innocent people were getting punched in the face as they were walking by. The next morning in Costa Maya there were a bunch of people sitting by the side of the ship with all of their luggage as they were kicked off the ship and their relatives were shipped off to Mexican jails. Carnival needs to learn a lesson here and not serve alcohol after a certain time and perhaps shut down the 18+ dance club before 3:00 a.m. Nothing good can come of drunk teenagers at 3:00 in the morning.
