The ship can accommodate up to 4,001 passengers across its 1,667 cabins, with a crew of 1,215 working around the clock to keep everything running smoothly.
What makes this ship particularly appealing is its sweet spot in Royal Caribbean's lineup - it offers many of the bells and whistles you'd expect from a modern cruise ship, but at a more reasonable price point than the brand's newest vessels.

Where does the Mariner of the Seas cruise?
Port Canaveral, Florida serves as the primary home base for the Mariner of the Seas, putting passengers within easy reach of some of the Caribbean's most beloved destinations.
Popular Itineraries
The ship frequently sails to the Bahamas, with stops at Nassau and Royal Caribbean's private island, Perfect Day at CocoCay. These shorter cruises (often 2-4 days) are perfect for first-time cruisers or those with limited vacation time.
Longer itineraries span 5-8 days and venture into different regions of the Caribbean:
- Western Caribbean: Often includes stops at Cozumel, Mexico and other Mexican ports
- Eastern Caribbean: Features destinations like St. Thomas, St. Maarten, and Puerto Rico
- Southern Caribbean: Reaches islands like Aruba, Bonaire, and Curacao
- Bermuda: Seasonal cruises to this unique mid-Atlantic destination
The variety of cruise lengths makes the Mariner particularly flexible - whether you want a quick weekend getaway or a week-long vacation, there's likely an itinerary that fits your schedule.
What's the ship's history and recent updates?
The Mariner of the Seas has quite a story behind it. After more than a decade of service, Royal Caribbean invested $120 million in a major 2018 refurbishment that breathed new life into the vessel. This upgrade added extra cabins, modernized existing spaces, and bumped the ship's gross tonnage up to its current 140,000 GT.
Like many cruise ships, the Mariner faced challenges during the COVID-19 pandemic. The crew experienced extended stays onboard due to travel restrictions, highlighting the complex logistics involved in operating these floating cities.
More recently, in 2023, the ship underwent another round of updates to keep pace with guest expectations and safety standards. These continuous improvements help explain why the Mariner remains competitive despite being over two decades old.
Is the Mariner of the Seas worth booking?
The Mariner of the Seas has earned a reputation as one of the better value propositions in Royal Caribbean's fleet. Passengers consistently praise the ship for delivering a solid cruise experience without the premium pricing of newer vessels.
What Makes It Special
The ship excels at providing variety - with so many activities and dining options, even repeat cruisers find new experiences each time they sail. The FlowRider surf simulator and ice rink are particular hits with families, while the specialty restaurants and bars satisfy adults looking for elevated experiences.
Things to Consider
Since the Mariner isn't Royal Caribbean's newest ship, some amenities might not be as cutting-edge as what you'd find on recently launched vessels. However, many cruisers actually prefer this - the ship has a proven track record, and any initial kinks have long been worked out.
The passenger space ratio of about 35 means you won't feel cramped, even when the ship is at full capacity. This is especially noticeable in the pool areas and main dining venues during peak times.
For first-time cruisers or those wanting to experience a large ship without paying top dollar, the Mariner of the Seas represents an excellent entry point into Royal Caribbean's cruise experience. The combination of reasonable pricing, diverse activities, and proven itineraries makes it a smart choice for many travelers.
