Discovery Class Size and Capacity
The Royal Caribbean Discovery class includes two ships, the Symphony of the Seas and the Wonder of the Seas, with a gross tonnage of approximately 228,000 GT and a length of about 362 meters. Each vessel accommodates up to 6,988 passengers at double occupancy, making them among the largest passenger ships in operation according to Forbes.
The Discovery class size exceeds that of the earlier Oasis class, with a wider beam of roughly 66 meters and 18 decks above the waterline. The ships feature 2,759 staterooms, including family suites and interior cabins, optimized for high passenger volume without exceeding port infrastructure limits.
Onboard Layout and Space Allocation
Inside the Discovery class size, public space totals over 18,000 square meters, with the Central Park boardwalk spanning two decks and hosting over 20 restaurants and bars. The ship layout uses a tiered atrium design to maximize vertical space, while the total water surface area includes multiple pools and a 1,050-square-meter solarium.
Staterooms and Balcony Distribution
Of the 2,759 cabins, 1,385 feature balconies, 974 are interior rooms, and 400 are suites, with family-oriented cabins comprising roughly 30 percent of inventory. The balcony ratio aligns with the broader Royal Caribbean fleet strategy of increasing outdoor private space per passenger.
Deck-by-Deck Breakdown
Deck 15 holds the highest concentration of passenger cabins, while decks 16 and 17 focus on entertainment venues, a theater, and the two-deck Royal Promenade. The lowest passenger decks house crew quarters, engine rooms, and technical areas below the waterline.
Comparison With Other Royal Caribbean Classes
Compared to the Freedom class, the Discovery class size offers 25 percent more passenger capacity and 40 percent more gross tonnage, while the Quantum class provides a slightly smaller 5,188-passenger capacity on a 168,666 GT hull. The Oasis class, with a 6,780-passenger capacity, remains the closest competitor in scale per SEC filings.
The Discovery class ships rank second in the global cruise fleet by gross tonnage, behind only the upcoming Icon class vessels under construction. Delivery of the Wonder of the Seas in 2022 completed the two-ship class, with no further vessels currently ordered under this design per Wikipedia.
