Royal Caribbean’s latest megaship, Harmony of the Seas, launched in May of this year to claim her crown as the largest cruise ship in the world. Among her many entertainment offerings is a full scale Broadway-style production of Grease. My adventure began two weeks before Harmony sailed, when I join her, with my hard hat firmly planted on my head, in a shipyard in St. Nazaire, France. We built a show while all around us the French workers built a ship. Chaotic and challenging, it turned out to be one of the greatest adventures of my life (not to mention a stunning production of this beloved show!) If your travels happen to take you aboard Harmony, be sure to check it out.
