The second ship in Princess Cruises' Sphere Class may be a doppelganger for her older sibling, 2024's Sun Princess, but the cruise line did make a few tweaks to optimize space in two popular dining venues and enhance the entertainment offerings. Accommodating 4,300 guests at double occupancy, Star Princess is a very big ship — the two Sphere-class vessels are the largest in the Princess fleet — and yet it is purposefully devoid of the flashy décor and adrenaline-rush activities of similarly-sized ships from other cruise lines.
Interior décor, mostly in a palette of warm neutrals and natural finishes with a few sparkly accents, is refined rather than loud. This reflects the preferences of a loyal Princess customer base (this is "The Love Boat" cruise line after all) that doesn't care about high-tech gimmicks or wow moments and instead prefers a pretty ship with a lively ambience and fun programming in a variety of entertainment venues.
The most dazzling spaces on Star Princess — The Sphere and The Dome — are airy and light-filled thanks to an outward-facing design that incorporates massive globe-like windows. This will be ideal when Star Princess embarks on Alaska itineraries in summer 2026. The rest of the ship consists of myriad smaller spaces accommodating 30 restaurants and bars. The main entertainment space is the Princess Arena, a circular theater that can seat 1,000 guests and be configured in three different ways.
