Spectrum of the Seas

Quantum Ultra is Royal Caribbean's label for Quantum-class ships built with modifications for the Asia-Pacific market. Spectrum was purpose-built for homeporting in Shanghai and subsequently Hong Kong, meaning the dining program, entertainment, and in-cabin amenities reflect a guest demographic that differs substantially from Caribbean or European sailings. The specialty restaurant lineup includes Jamie's Italian (standard Quantum-class addition), but also regionally focused Asian dining concepts absent on Western-market ships.

The technology package is the most striking aspect for first-time Quantum-class passengers. The North Star is a glass-and-steel observation capsule that rises 300 feet above sea level on a robotic arm — the ship equivalent of a ferris wheel, offering 360-degree ocean views when you're on the capsule and dramatic visual impact when you're watching from the deck. RipCord by iFly is a genuine indoor skydiving simulator, not a gimmick: the vertical wind tunnel uses the same physics as outdoor skydiving, and the experience takes about 15 minutes from briefing to flight. Both are complimentary with reservation.

SeaPlex — the ship's indoor sports hall — converts between roller skating, basketball, bumper cars, and a circus school throughout the voyage. Two70° is an entertainment venue at the stern that uses six Roboscreens (screens mounted on robotic arms that move during performances) and a 270-degree glass window backdrop. It functions as a casual lounge during the day and a performance space in the evening.

The guest who fits Spectrum: travelers departing from Asia-Pacific ports who want the full Royal Caribbean technology experience in a ship calibrated for the regional market. Travelers who prefer more intimate ships or who find the technology focus overwhelming may prefer Radiance-class options.
