Princess and Royal Caribbean target different cruise philosophies. Royal Caribbean builds the biggest ships in the world and fills them with waterslides, surf simulators, ice rinks, and onboard neighborhoods designed to keep you entertained without ever leaving the ship. Princess builds mid-sized premium ships with MedallionClass wearable technology and designs the experience around the destinations you are visiting, not the ship itself.
For Alaska, the answer is clear: Princess is the specialist and has been for decades. For Caribbean family vacations on the biggest possible ship, Royal Caribbean wins on scale and CocoCay. For couples and mature travelers who want a refined onboard pace with the most technologically integrated cruise experience, Princess’s Sphere class ships and MedallionClass system deliver something Royal Caribbean does not offer.
At a glance
The spec table above pulls any numeric facts directly from our structured dataset. Where a value reads “Not published,” it means we have not independently verified that number against the line’s own page, so we do not guess. Always confirm final baggage policies, dress code frequency, and cabin square footage directly with the line before booking.
What does Princess do better than Royal Caribbean?
Princess wins on Alaska expertise, MedallionClass wearable technology, a calmer onboard atmosphere, and flexible formal night scheduling.
- Alaska dominance. Princess is the cruise line that defined Alaska cruising. More Inside Passage departures from Seattle than any competitor, exclusive land-and-sea tour packages combining Gulf of Alaska cruises with Denali National Park rail tours, and a decades-long relationship with Alaska communities and excursion operators. Royal Caribbean sails to Alaska, but Princess owns the market. If Alaska is the destination, Princess is the default.
- MedallionClass technology. Every Princess guest receives a small wearable medallion that enables keyless cabin entry, location-based food and drink delivery to anywhere on the ship, digital wayfinding, and personalized service. Order a drink from your deck chair and a crew member finds you. Walk to your cabin and the door unlocks as you approach. Royal Caribbean has invested in its app, but nothing in the Royal Caribbean fleet matches MedallionClass as a fleet-wide integrated system.
- Onboard atmosphere for couples and mature travelers. Princess’s pool decks are calmer. The entertainment leans toward enrichment programming, live music, and Movies Under the Stars rather than water parks and surf simulators. The passenger demographic skews older than Royal Caribbean’s family-heavy ships. For couples seeking a relaxed pace, Princess is the more comfortable environment.
- Formal night structure. Princess designates formal nights only on cruises of 7 nights or longer (zero formal nights on cruises of 6 nights or fewer). This gives shorter-sailing guests a completely dress-code-free experience while preserving the option for dressing up on longer itineraries. Royal Caribbean designates Dress Your Best nights starting at 5-night sailings.
- US homeport breadth for a premium line. Princess sails from PortMiami, Port Canaveral, Fort Lauderdale, Galveston, Long Beach, and Seattle. For a premium-positioned cruise line, this is unusually wide domestic coverage.
What does Royal Caribbean do better than Princess?
Royal Caribbean wins on ship scale, onboard activity count, the CocoCay private island, fleet variety, and entertainment production value.
- Ship scale and onboard activities. Icon of the Seas has 8 neighborhoods, the most waterslides of any cruise ship, a surf simulator (FlowRider), ice skating rink, rock climbing wall, Central Park, and a wider range of activities than any Princess ship. The gap in onboard entertainment is significant. If you want to stay busy without leaving the ship, Royal Caribbean offers more to do.
- Perfect Day at CocoCay. Royal Caribbean’s private Bahamas destination is the gold standard for private islands in mainstream cruising. Thrill Waterpark, overwater cabanas, a zip line, and a helium balloon ride provide a full day of activities. Princess does not operate a private island destination.
- Family programming depth. Adventure Ocean kids clubs, teen programs, splash parks, and family-oriented entertainment make Royal Caribbean the stronger pick for families with children. Princess welcomes families but does not design its ships around them the way Royal Caribbean does.
- Fleet variety. Royal Caribbean operates 29 ships across 7 ship classes (Icon, Oasis, Quantum, Voyager, Freedom, Vision, Radiance), each with a distinct personality. Princess operates 17 ships across 2 current classes (Sphere and Royal). Royal Caribbean’s fleet range means more options for matching a ship to your preferences.
- Entertainment scale. Royal Caribbean’s Broadway-style productions, ice shows, AquaTheater performances, and high-energy nightlife programming are higher-budget and more varied than Princess’s entertainment options. If shows and nightlife are important to your cruise experience, Royal Caribbean delivers more.
Where are Princess and Royal Caribbean roughly equal?
Both lines sail similar Caribbean itineraries, designate dress-up evenings by sailing length, overlap in pricing, and offer tiered loyalty programs.
- Caribbean itineraries. Both sail extensively from Florida to the Bahamas, Eastern Caribbean, and Western Caribbean. On shared ports of call, the destination experience is the same.
- Dress-up evenings. Both designate dress-up evenings scaled by sailing length. Princess calls them formal nights. Royal Caribbean calls them Dress Your Best. Neither requires black-tie. Both allow casual alternatives in buffet venues on formal evenings.
- Pricing on comparable itineraries. For 7-night Caribbean sailings, pricing frequently overlaps. Princess’s premium positioning and Royal Caribbean’s mega-ship premium both push into the same price range. Compare current fares directly.
- Loyalty programs. Princess’s Captain’s Circle and Royal Caribbean’s Crown & Anchor Society both reward repeat cruisers with tiered benefits (priority boarding, onboard credits, suite lounge access at higher tiers). Both are sailing-count-based rather than points-based.
Which one should you book?
- Book Princess if you are cruising to Alaska and want the industry leader, you value MedallionClass wearable technology, you prefer a calmer onboard pace, or you are a couple seeking a refined atmosphere without the family-dominated energy of a mega-ship.
- Book Royal Caribbean if you want the biggest ship in the world (Icon of the Seas), you are traveling with children who want waterslides and kids clubs, Perfect Day at CocoCay is a must-do, or you want the most onboard activities and entertainment variety.
- Book Celebrity instead if you want the culinary quality and modern design of a premium line with the backing of the Royal Caribbean Group. Celebrity’s Edge class ships are the premium alternative to Royal Caribbean’s mainstream fleet. See our Celebrity vs Princess comparison for context.
What still needs verification before you book
Policies change without notice. Before you book, independently confirm:
- Alaska itinerary availability and pricing for your specific dates on both lines (Princess deploys more ships but sells out Alaska early).
- MedallionClass features on your specific Princess ship (all ships support MedallionClass, but the app experience varies by ship age).
- CocoCay or private island inclusion on your specific Royal Caribbean itinerary (not all sailings include a private island stop).
- Formal night frequency for your itinerary length on both lines.
- Current drink package and Wi-Fi pricing on both lines, which changes regularly.
Bottom line
Princess and Royal Caribbean compete for cruise travelers but rarely for the same cruise traveler. If you want a destination-focused cruise with the best technology in the industry and a pace that lets you enjoy the ports, Princess is the pick. If you want the most ship, the most activities, and the most entertainment packed into a single floating vacation, Royal Caribbean is the pick. Both are well-run cruise lines with modern fleets and strong loyalty programs. The choice is whether the destination or the ship itself is the point of your trip.
