The world's largest cruise line says a much-publicized pilot program to eliminate the practice launched in July on the 3,690-passenger Carnival Breeze was a big success, and it'll be rolled out fleetwide over the coming weeks.

"It has been a subject discussed over and over again, and it has been so because it continues to be a concern," Carnival senior cruise director John Heald wrote on his Facebook page in July.
