Starwater is the production that exists specifically to justify the Two70 venue on Quantum-class ships. The Two70 is a multifunctional entertainment space at the ship's stern, defined by floor-to-ceiling panoramic windows, six robotic video screens on motorised arms that move in sync with the performance, a Vistarama projection system across 18 projectors creating a seamless 100-foot-wide digital canvas on the aft windows, and rigging above for aerial performers. Starwater uses all of it, simultaneously, and the result is a show that simply cannot be replicated in any other venue on any other ship.
The technology
The robotic screens are the element that most reviews focus on, and they earn that attention. The six screens move through the performance space during the show, rotating and repositioning to create different stage configurations while performers interact with both the screens and the live projection backdrop behind them. The choreography is designed around the screens' movements as much as the music, which gives the show a visual grammar that takes a few minutes to calibrate to and then becomes deeply satisfying to track.
The first time a robotic screen moves toward a performer and they interact with it in real time, something shifts. You understand what the Two70 was built to do.
Forever Karen's review of a Quantum of the Seas Alaska sailing describes the Two70 shows as unique and sensational, noting that the six robotic screens and aerial performances at night were unlike anything encountered in other venues. That assessment is consistent across Cruise Critic reviews and the Royal Caribbean Blog coverage of Starwater as it moves into the US market for the first time in the 2025 to 2026 season.
Pre-booking is not optional
Starwater sells out on every sailing. The Two70 has a much smaller capacity than the Royal Theater and the show's reputation has been established long enough that word of mouth fills it consistently. Pre-book through the app the moment your window opens. If you miss a booking, arrive at the Two70 at least 20 minutes before the show and join the standby line. Many booked guests do not show, and the staff release standby seats about 10 minutes before the start. It is worth waiting for.
The Vistarama projection system is also used for non-show programming during sea days, transforming the Two70 into an immersive viewing environment for films, nature content, and other programming. The venue is worth visiting outside of show hours to understand the scale of the technology before Starwater puts it to its full use.
Sit toward the centre of the Two70 for the best angle on the robotic screen choreography. The show works from any seat in the venue but the central position gives you the full geometry of the screen movements in relation to the performers and the projection backdrop simultaneously.
