Symphony of the Seas is the fourth ship of Royal Caribbean's Oasis class, built by Chantiers de l'Atlantique at Saint-Nazaire in France and delivered in 2018 at a cost of roughly US$1.35 billion. On entering service she claimed the title of the world's largest cruise ship, a distinction she held from 2018 until Wonder of the Seas surpassed her in 2022. At about 228,081 gross tons and 361 metres long across eighteen decks, she carries more than 5,500 guests at double occupancy and over 6,600 at maximum, served by roughly 2,200 crew.

Built on the mature Oasis template, she features the signature seven neighborhoods, including the live-planted Central Park and the carnival-themed Boardwalk with its hand-carved carousel. Her attractions include a full ice-skating rink, the ten-story Ultimate Abyss dry slide, the three-slide Perfect Storm waterpark, dual FlowRider surf simulators, twin rock-climbing walls, a zip-line, and a 1,400-seat main theater. She also debuted the Ultimate Family Suite, a two-story accommodation with an in-cabin slide and its own cinema, aimed at the top of the family market.

Symphony of the Seas marked a milestone in Royal Caribbean's christening traditions: at her 2018 naming she was blessed not by a single godmother but by the PenaVega family, actors Alexa and Carlos PenaVega and their son, whom the line designated its first-ever 'Godfamily.' Her maiden voyage sailed from Barcelona in the spring of 2018 before she crossed to her Florida base.

Registered in Nassau, Bahamas, and homeported in Miami, Symphony of the Seas sails Caribbean itineraries and remains in active service, a flagship-caliber vessel that for four years reigned as the largest passenger ship afloat.

Getting around - smart elevators: Royal Caribbean has been rolling out destination-dispatch "smart elevators" across its largest ships, including the Oasis class. Where fitted, guests select their deck at a console outside the elevators and are directed to a specific lettered car (A, B, C, and so on) rather than pressing a button inside the car; the system groups riders by destination to reduce waiting time.
