History
AI-generated

Harmony of the Seas is an Oasis-class cruise ship built by Chantiers de l'Atlantique in Saint-Nazaire, France, for Royal Caribbean International. The ship is named after the Harmony module on the International Space Station and was christened by Miami-Dade County teacher Brittany Affolter. During her preview cruises in Southampton, passengers reported ongoing construction issues including lack of hot water and unopened attractions, though these problems were resolved by the maiden voyage departure from Southampton to Barcelona.
