Carnival Cruise Lines named Ruben Rodriguez executive vice president of ship operations. He had been executive vice president of marketing and guest experience.

Rodriguez will now oversee hotel, technical and marine operations while retaining responsibility for guest experience.

The marketing, revenue management and deployment departments that Rodriguez previously led will now report directly to Carnival CEO Gerry Cahill.

Rodriguez has been with Carnival for just over two years. He arrived in October 2007 to take on the newly created marketing position. Before that, he was a partner and managing director in the Miami office of Boston Consulting Group, a management consulting firm.

"Ruben has worked very closely with ship operations in his product development role, and we believe there are significant benefits to uniting all of those functions under one leader," Cahill said in a statement.
