Mariner of the Seas

Built for guests who love active holidays, Mariner of the Seas pairs laser tag and waterslides with speciality dining and a choice of cabins to suit solo travellers, couples and larger families alike. Since 2003, the ship has carried holidaymakers to the Caribbean and beyond, and a thorough Royal Amplified makeover has kept it feeling current for a new generation of cruisers.

Welcome to Mariner of the Seas

Mariner of the Seas entered service in 2003 as one of five Royal Caribbean Voyager Class ships. A $120 million Royal Amplified refurbishment in 2018 reshaped much of the ship, adding a variety of activity facilities and a host of new restaurants. Spread across 15 decks, the Mariner of the Seas cruise ship carries around 3,114 guests at double occupancy and is served by a crew of nearly 1,185.

Guests booking a Mariner of the Seas cruise can enjoy short Western Caribbean getaways from Galveston, Texas, calling at Costa Maya and Cozumel. Across the 2026-27 winter season, it will explore Cozumel, George Town and Falmouth before heading across the Atlantic for a season in the of Mediterranean and Western Europe. Wherever it sails, Royal Caribbean's Mariner of the Seas offers a range of onboard activities, dining, and entertainment to enjoy.
