The fourth cruise ship in Royal Caribbean's Oasis Class, which Royal Caribbean is calling "Oasis IV", is scheduled for launch in spring of 2018. Various sources indicate the ship will be called Symphony of the Seas. It's under construction at the STX France shipyard.
Like sister ship Harmony of the Seas, Oasis IV will carry 5,479 passengers, making it slightly larger than its 5,400-passenger classmates, Oasis of the Seas and Allure of the Seas. (All four ships are part of the line's Oasis Class, despite their size differences.)
Oasis-class ships are categorized by their vast size and neighborhood layout, a concept first introduced on Oasis of the Seas in 2009. Among the seven neighborhoods we expect to be onboard Oasis IV are Boardwalk, Central Park, Entertainment Place, the H2O Zone and Kid's Avenue.
Besides the neighborhoods, Oasis IV will feature a mix of firsts from both the Quantum and Oasis classes. Although no new concepts have yet been announced for the ship, Royal Caribbean is sure to unveil some new-to-the-line experiences over the next two years.
In terms of cabins, expect to see a large variety of choices, from solo cabins to expansive suites, as well as Boardwalk-, Promenade- and Central Park-view rooms. We also expect that most, if not all, inside cabins will feature virtual balconies.
