Ocean Spectrum is the first "superquantum series" cruise ship in Royal Caribbean. Since it is an upgraded version, its tonnage and passenger capacity are larger than Quantum, and its entertainment facilities are more perfect. For example, in the guest room, the duplex suite on Quantum is known as the "luxury house on the sea". On the basis of retaining these characteristics, Spectrum has set up a royal maritime mansion on the 13rd floor to the 16th floor to provide exclusive rooms, dining and leisure areas for suite guests. Another highlight is the addition of a perfect family suite, which can provide private living space for three generations of 11 people, and the room facilities are also perfect. The restaurant has also been upgraded, with a larger capacity, and Sichuan cuisine has been introduced. There is also an entertainment upgrade, and a karaoke room named Star Moment will be added to the spectrum number, so that guests can experience the feeling of stars singing with friends and relatives.
