Cruise ships · Royal Caribbean
Mariner of the Seas
Royal Caribbean · Voyager Class
What it's like
- A very large ship: it usually feels steady, with mild motion in normal seas.
- Lots of room per guest, so pool decks and lines feel calmer than on most ships.
- Built 2003, refurbished 2018.
- A kids' club for families, plus adults-only space for a quieter escape.
Highlights: The original pioneers of the Royal Promenade, rock-climbing walls, ice-skating rinks, mini-golf courses, and amplified water slides on select upgraded hulls.

General tips for any ship
- For the least motion, choose a cabin low and in the middle of the ship (midship), near the central elevators.
- For quiet, avoid cabins directly under the pool deck, buffet, theater or nightclub, and right beside the elevators or service areas.
- Cabins at the very front feel the most pitching in rough seas; cabins at the very back can feel some vibration from the engines.
- Some balcony cabins have partly blocked views (lifeboats, for example); the deck plan marks them, so check before you book.
For the exact layout, see the official deck plan for Mariner of the Seas on Royal Caribbean's website ↗.
