Approximately 3,000 craftsmen spent some 8 million working hours on the ship, and a total of 20,000 people were directly or indirectly involved in her design, construction, and fitting out. In total, 300,000 pieces of steel were assembled into 94 "blocks" off of the drydock, which were then stacked and welded together to complete the hull and superstructure. She is so much larger than the ships that Chantiers normally build that the shipyard treated her as "1.6 ships."

Construction was completed on schedule. Due to the size of the ship, the luxury of materials, and the fact that, due to her nature as an ocean liner, she required 40% more steel than a standard cruise ship, the final cost ended up being approximately $300,000 US per berth - nearly double that of ships such as Voyager of the Seas
