Royal Carribean International has apologized to passengers who had their cruise-going experience ruined by 1,300 rowdy conference attendees, whose idea of fun reportedly entailed bringing burlesque dancers and women dressed as Playboy bunnies to swarm public areas of the vessel.

Last month, 1,300 employees from Indian tobacco company Kamla Pasand boarded Voyager of the Seas ship in Sydney, Australia. The Sun reported that the employees took over the pool deck, bars, bingo halls, and buffets—leading many families to seek refuge in their cabins.

“It was almost like a huge bucks party—a bucks night for 1,200 people,” passenger Cassandra Riini told Australian news program “A Current Affair” of the risqué shenanigans. “Their doors would be open and you would walk past and be like what am I going to be looking at when I walk past this door?”

The program noted that the rowdy workers accounted for more than a third of the passengers aboard the 140,000-ton ship.

In light of the controversy, Royal Carribean launched an independent investigation and ultimately issued refunds to droves of unsatisfied customers.

“During [Voyager of the Seas’] three-night sailing on September 6th, a group onboard caused complaints to some of our guests. We were quickly made aware and provided them with a satisfactory solution,” Royal Carribean managing  Susan Bonner said in a statement

“We operate with the safety of our guests and crew as our highest priority, and are currently looking into all guest feedback regarding this incident to ensure it does not happen again.”
