Royal Caribbean is built for scale and thrills: the biggest ships, the most waterslides, and features like sky-diving simulators and observation pods that exist nowhere else. Princess is built for a calmer, more classic cruising style, with enrichment programming and a loyal repeat-passenger base. Pick Royal Caribbean if size and adrenaline are the draw. Pick Princess if you want a quieter ship with a more traditional pace.
Ships and fleet
Royal Caribbean operates the largest ships in the world, including the Icon-class and Oasis-class megaships, alongside smaller and older classes still sailing shorter itineraries. The line's newest ships are essentially floating small cities, with neighborhoods, multiple pool decks, and features built specifically to be photographed and shared.
Princess runs a smaller, more uniform fleet centered on mid-size Royal-class and Grand-class ships, with its newest Sphere-class ships (Sun Princess and Star Princess) representing a significant jump in scale for the brand while still trailing Royal Caribbean's largest vessels. Princess has a long history in Alaska that Royal Caribbean does not match in depth.
Dining
Royal Caribbean offers a traditional main dining room and buffet alongside a long list of specialty restaurants that vary by ship, some of the newest ships have a dozen or more dining venues, many carrying an extra charge. Dining packages that bundle multiple specialty meals are worth pricing out if you plan to eat outside the main dining room often.
Princess dining leans on its Medallion wearable device, which lets guests order food and drinks from anywhere onboard without waiting in line. The main dining room experience is more central to the Princess identity than to Royal Caribbean's, with specialty venues playing a smaller supporting role.
Cabins
Royal Caribbean's newest ships introduced loft suites and private "neighborhood" cabin clusters with dedicated pools and concierge service, a tier well above standard balcony cabins. Family-connecting configurations are common on the larger ships, reflecting the line's family-forward positioning.
Princess offers a full range from interior to balcony to suite, with the Sphere-class ships adding new cabin categories tied to the ship's distinctive dome structure. Suite perks are tied into the line's Captain's Circle loyalty program, rewarding repeat cruisers over time.
Who it suits
Royal Caribbean suits families, groups of friends, and thrill-seekers who want the biggest ship features available anywhere in cruising. Princess suits couples, older travelers, and destination-focused cruisers, especially those sailing Alaska, who want a calmer pace and enrichment-style programming.
Who should skip it
Skip Royal Caribbean if you want a quiet ship with minimal crowds and noise, the biggest ships in the fleet are built for exactly the opposite experience. Skip Princess if you want nonstop activity and the biggest onboard attractions, since its programming favors a slower pace over adrenaline.
Price and value
Royal Caribbean's price range is enormous, from budget interior cabins on older ships to premium suite categories on the newest megaships that rival luxury-line pricing. Overall base fares tend to be competitive for the amount of ship you're getting.
Princess pricing sits in a similar mainstream-to-premium range, often reflecting the added cost of longer Alaska and repositioning itineraries where the per-day rate can actually undercut short, splashy Caribbean sailings elsewhere.
Booking and value
Royal Caribbean's fare structure spans the widest range in mainstream cruising, from budget interior cabins that can undercut nearly every competitor to neighborhood-style suites priced closer to a luxury line. That spread means "Royal Caribbean is expensive" and "Royal Caribbean is cheap" can both be true statements depending entirely on which ship and cabin category you're pricing, so shopping by ship class matters as much as shopping by date. Add-ons, specialty dining, drink packages, and excursions, stack on top of the base fare regardless of cabin tier.
Princess bundles more of its value proposition into loyalty over time. The Captain's Circle program rewards repeat cruisers with escalating perks, and longer itineraries, particularly in Alaska, often carry a better effective per-day rate than the same number of nights spent on a shorter, splashier Caribbean sailing elsewhere. Land-and-sea packages that combine a cruise with a rail or lodge stay are a distinctly Princess-flavored add-on that doesn't have a direct equivalent on Royal Caribbean.
Both lines run frequent promotional pricing, and neither reliably undercuts the other across every itinerary, comparing the same sailing dates and cabin categories directly remains the only reliable way to know which is actually cheaper for a specific trip.
Itineraries and home ports
Royal Caribbean sails from the widest home port network of any mainstream line, covering nearly every major North American port plus a large international footprint across Europe, Asia, and Australia. Itinerary lengths run from short three-night getaways to multi-week repositioning cruises, and the line's private destination, Perfect Day at CocoCay, anchors a large share of its Caribbean sailings.
Princess sails from a narrower set of home ports but goes deeper into specific destinations, especially Alaska, where Seattle and Vancouver departures connect to the line's own rail and lodge network for a more integrated land-and-sea experience. Princess also runs meaningful Mexican Riviera, Panama Canal, and transatlantic itineraries that lean more toward destination immersion than quick getaways.
A traveler who wants the broadest possible choice of departure port and trip length will find more options with Royal Caribbean. A traveler specifically planning an Alaska trip, or wanting a longer, slower itinerary, will generally find Princess's destination-specific infrastructure the stronger fit.
The deciding factors
A family or group of friends chasing the biggest onboard features, waterslides, rock walls, and observation decks should book Royal Caribbean, ideally one of its newest Icon-class or Oasis-class ships. A couple or retired traveler planning an Alaska cruise who wants naturalist programming and a calmer ship should book Princess, given how much further its Alaska infrastructure extends beyond the ship itself.
A first-time cruiser unsure what kind of trip they want may do well starting with Royal Caribbean, since its itinerary and ship-size range makes it easier to dial in a preference for next time. A repeat cruiser who has already sailed a few mainstream lines and wants a quieter, more enrichment-focused pace, without full luxury-line pricing, should give Princess a serious look.
A milestone celebration with a wide age range across the group tends to fit Royal Caribbean's broader venue mix better, since there's more for each subgroup to do independently. A longer, slower trip built around scenery and destinations rather than onboard activity, particularly anything Alaska-adjacent, favors Princess by a wide margin.
Common questions
Which line has bigger ships?
Royal Caribbean, by a wide margin. Its Icon-class and Oasis-class ships are among the largest passenger ships ever built, well beyond Princess's largest Sphere-class vessels.
Which line is better for Alaska?
Princess has the deeper Alaska track record and owned land infrastructure. Royal Caribbean sails Alaska too, but it's a smaller part of the overall itinerary mix.
Which line has better loyalty perks for repeat cruisers?
Both have strong programs, but Princess's Captain's Circle is often cited for how noticeably suite perks improve at higher tiers, which matters more to travelers who cruise the same line repeatedly.
Which line has a wider range of home ports?
Royal Caribbean, with the broadest home port network in mainstream cruising across North America, Europe, Asia, and Australia. Princess covers fewer ports but goes deeper into specific regions like Alaska.
Is Princess a good fit for families?
It can be, but Royal Caribbean's family-forward design, kids' clubs, and waterpark features are generally the stronger match for families with young kids specifically looking for onboard activity.
The real decision here is pace: fast and big versus slow and classic. Compare live pricing for both on current cruise deals, then compare sailings and prices to line up itineraries by season. Once booked, track any cruise ship live to watch your ship approach port. For more on either brand specifically, see our Royal Caribbean review or Princess Cruises review.
