Back-to-Back Cruises on Quantum of the Seas

Every row below is a real pair of sailings on Quantum of the Seas herself, where the second leg leaves the day the first one returns — so you stay aboard for 7 to 30 nights instead of flying home in between. There are 56 of them cached right now, out of Brisbane, Singapore and Seattle, departing between Oct 22, 2026 and Mar 19, 2028. The most common combination is 7 nights (18 of them). Fares are the lowest cached interior all-in price per guest for both legs together, before any casino offer is applied.

About the Quantum Class

The tech-forward class: the North Star observation capsule that lifts you 300 feet above the sea, RipCord by iFly skydiving, bumper cars in the SeaPlex, and robotic bartenders. Quantum ships are a favorite for Alaska and Asia.
