About Mariner of the Seas

Mariner of the Seas is a Voyager Class ship that entered service in 2003 and was transformed by a $120 million Royal Amplified refit in 2018, which added The Perfect Storm racer waterslides, Battle for Planet Z glow-in-the-dark laser tag, the Royal Escape Room, Splashaway Bay, Jamie’s Italian, Izumi Hibachi & Sushi, Playmakers Sports Bar & Arcade, The Bamboo Room tiki bar and new staterooms. A 2026 dry dock added pool-deck casitas and a general refresh. At about 139,900 gross tons she carries roughly 3,344 guests on 14 guest decks.

She suits families and groups who want almost everything a bigger Royal Caribbean ship offers, from the FlowRider, ice rink and rock climbing wall to a wide specialty dining lineup, on a ship that is easy to navigate. The Royal Theater, Studio B ice shows under the big top, Boleros, Playmakers and the Bamboo Room cover the evenings, and the adults-only Solarium and Vitality Spa give grown-ups a quiet escape.

Mariner sails short Western Caribbean cruises from Galveston through fall 2026, repositions to New Orleans in November 2026 for 7-night Western Caribbean sailings to Cozumel, George Town and Falmouth through April 2027, then crosses to Europe for summer 2027 from Lisbon, Barcelona, Rome (Civitavecchia) and Ravenna, including a July 2027 solar eclipse sailing from Barcelona. SmartCruiser adds bonus onboard credit on her sailings where Royal Caribbean allows it, not available booking direct.
