Santa Clarita’s Princess Cruises has appointed a new head of guest operations to help drive its marketing initiatives and offer new guest experiences. The cruise line announced this week it has promoted Mario Siebaldi, former vice president of guest services and technology, to senior vice president of guest operations effective immediately. Siebaldi brings 25 years of experience working for Princess Cruises to the position, and is now in charge of spearheading the lines’ “Come Back New” initiative, which includes onboard experiences exclusive to Princess such as its Discovery at Sea and North to Alaska onboard programs. “Mario is a respected leader in our organization and brings an in-depth understanding of our operations to his expanded role,” Rai Caluori, executive vice president of guest experience and product development said in a statement. “With his continued dedication and commitment to the Princess brand, Mario will be integral in supporting the fleet to ensure our guests ‘come back new.’”
