The ship
Lead next-gen Sphere — Piazza flagship Princess
Sun Princess is the lead next-generation Sphere-class Princess from 2024: larger than Sky’s Royal Sphere trio at about 4,300 guests, MedallionClass standard, and a glass-domed social heart built for the new Piazza era. Calmer than Oasis, newer than Royal-class.
Main dining, Horizon Court and International Café sit in the included dining. Specialty nights are worth planning — among them Crown Grill, Sabatini’s and Sphere specialties. OceanNow via Medallion is part of the convenience habit.
Evenings run through the evolved Piazza under glass, cocktail and jazz lounges, and Princess theatre productions. Daytime is pools, kids’ clubs and splash areas for multi-gen, Sanctuary adults-only (often extra) and Lotus Spa extras. MedallionClass cabin unlocks throughout.
Sun is Princess’s new flagship language: Sphere glass, Medallion convenience, and a deck plan still calmer than Oasis — budget specialty nights and Sanctuary.
On board
New Sphere on board
- 01
Restaurant choice
Main dining, Horizon Court and International Café sit in the included dining. Specialty nights — Crown Grill, Sabatini’s and Sphere specialties among them — are worth booking on sea days. Medallion ordering helps; covers still sit outside many prices. Price drink packages against the nights you will actually use.
- 02
Shows and Piazza
Princess theatre productions and Piazza entertainment under glass. Programme changes by season — check your sailing. Movies Under the Stars and Dome-style moments appear in the Sphere soft product. Book spa or specialty slots on sea days before the popular times vanish. Claim shade early on warm sea days if a lounger matters to you.
- 03
After dark
Cocktail and jazz lounges cover the evening at Princess contemporary volume. Casino and Piazza bars fill the midship wander. Price drink packages against the nights you will use. Claim shade early on warm sea days if a lounger matters to you. Sign kids into clubs early on school-holiday embarkation afternoons.
- 04
Deck and Sanctuary
Pools and splash areas for families; Sanctuary adults-only (often extra) for quieter sun. Lotus Spa thermal extras — book ahead on sea days. Arrive early for centre seats on sea-day production nights. Sign kids into clubs early on school-holiday embarkation afternoons. Treat brochure show titles as current-season colour — programmes change.
- 05
Kids and MedallionClass
Kids’ clubs and teen spaces run at Sphere scale. MedallionClass unlocks and OceanNow delivery are standard. School-holiday weeks feel full — sign in early. Price drink packages against the nights you will actually use. Treat brochure show titles as current-season colour — programmes change.
Crown Grill
Crown Grill is the classic specialty steak room and one of the pricier covers on Sun Princess. Quieter and more dressed-up than the buffet or main dining rooms. Go here when you want a splurge dinner, not a cheap filler night.
Sabatini’s
Sabatini’s is the Italian specialty night — pasta and trattoria plates as a paid evening rather than the included main rooms. Mid-spend specialty: less than the steakhouse, more of an occasion than the buffet. Book early on sea days if Italian is your treat.
New Sphere specialties
The Sphere is Sun Princess’s glass-domed social heart — Piazza-style energy under a bigger roof. Included as a gathering space. Best when you want atrium buzz without committing to a theatre seat.
Main dining & Horizon Court
Main dining & Horizon Court — the big casual option for breakfast, lunch and low-fuss evenings on Sun Princess. Included in the included dining and usually the quickest seat on a port morning. Ideal if you prefer self-serve over a long dining-room sitting.
International Café
International Café covers coffee, light bites and gelato in the Piazza — some items included or low-cost, fancy coffees often extra. Perfect between meals when you do not want a full restaurant.
Main theatre
Main theatre is the main house for Sun Princess’s production nights — cruise-stage spectacle sized for a megaship, not a West End transfer. Titles change by season, so check your sailing. Included with the cruise; grab a centre seat on night one if the headline matters.
The Sphere
The Sphere is Sun Princess’s glass-domed social heart — Piazza-style energy under a bigger roof. Included as a gathering space. Best when you want atrium buzz without committing to a theatre seat.
Cocktail lounges
Cocktail lounges covers live music and drinks at conversation volume — the rooms many guests actually plan around beyond the main theatre. Drinks sit outside the simple cruise. Best after the curtain when you want the night to continue gently.
Movies Under the Stars
Movies Under the Stars turns the pool deck into an evening cinema — blankets, popcorn energy and a big screen under the sky. Included once you are on board. Ideal for a low-fuss night when you do not want the main theatre.
Lotus Spa
Lotus Spa sells treatments and thermal-suite access as a day pass or package — not in the simple cruise. A calmer daytime reset than the pool deck. Book ahead on sea days if heat loungers and steam are your plan.
Fit
Who she is for
- UK bookers who want the newest Sphere-class Princess — glass Piazza, MedallionClass, Crown Grill — without Oasis neighbourhood hiking.
- Multi-gen families who will use kids’ clubs, Sanctuary for the adults and at least one specialty night.
- Not the ship if you want go-karts, Fun Ship volume, or true luxury suite butlers as the whole brief.
Where
Where Sun Princess tends to go
Early seasons favour Mediterranean and Caribbean patterns as Princess builds Sphere-class deployments. Confirm the current homeport.
Treat this as the ship’s range, not a fixed timetable. When this guide is public, sailings with two or more UK agent prices will sit at the bottom.

What the brochure skips
- Specialty dining, drinks packages, Sanctuary and spa sit outside many prices — budget them before you lock a cabin.
- Compare UK agents on the same sailing — same ship, same date, cruise-only, two sharing.
