Star Princess
Star Princess is Princess's newest flagship class — the Sun-class design with the full next-generation Princess experience
Star Princess (2025) is the second Sun-class Princess ship, following Sun Princess (2024). At approximately 4,300 guests, Star Princess represents Princess Cruises' largest class and most contemporary design. Key features include The Dome — a retractable glass sunlit structure that becomes the ship's social center in variable weather — the Sun Club Deck, a redesigned Sanctuary, and the full MedallionClass technology ecosystem integrated from launch rather than retrofitted. Star Princess sails Caribbean, Mediterranean, and other itineraries in her early years of service.
Star Princess arrived in 2025 as the second iteration of Princess Cruises' Sun-class, which launched with Sun Princess in 2024 and represents the line's most significant design evolution in a decade. The Sun-class is Princess's answer to where the market had moved: a ship at 4,300 guests with a design philosophy emphasizing light, social space, and technology integration rather than novelty attractions.
The Dome is the Sun-class's defining architectural feature. A retractable glass structure at the ship's center creates an enclosed social space that functions as an adult social hub, pool area, and entertainment venue depending on the configuration and weather. In conditions where the main pool deck is impractical — northern latitudes, rough seas, early-season cold — The Dome converts to a covered outdoor-adjacent experience without the closed-in feeling of a traditional ship atrium. The concept reflects Princess's historical strength in Alaska and Northern Europe sailings, where weather-adaptive spaces have long been valued by the line's guests.
MedallionClass technology was designed into Star Princess from the keel up rather than retrofitted. The OceanMedallion wearable ecosystem — contactless cabin access, location-aware drink and food ordering, app-based wayfinding — performs more reliably when the sensor infrastructure is part of the original build. Star Princess guests picking up the technology for the first time will find it more intuitive than the version that runs on older retrofitted ships.
The Sanctuary — Princess's premium adults-only sun deck — has been redesigned for the Sun-class in a larger format. The reservation-required, attended space that proved commercially successful on the Grand and Royal-class ships remains, expanded to accommodate more guests while preserving the separation from the main pool deck that defines its value. The Sanctuary on Star Princess carries forward what the concept has always delivered: a genuinely quieter outdoor option in a category where that's otherwise hard to find.
The honest note: Star Princess is a new ship in the catalog, which means long-term passenger reviews are limited. The Sun-class design represents a significant departure from Princess's Royal-class ships that many current Princess loyalists know well, and the experience will feel different in ways that go beyond the larger size. Guests booking Star Princess specifically for the Sun-class features — The Dome, the redesigned spaces, the technology integration — are booking intentionally. Guests who prefer the familiar Royal-class configuration may want to verify that the Sun-class suits them before committing to a Star Princess sailing.
