Mariner of the Seas is the fifth ship built in Royal Caribbean's Voyager class. Her sisters are Voyager of the Seas, Explorer of the Seas, Adventure of the Seas and Navigator of the Seas.
The Voyager class ships are impressive ships. Although they are no longer the largest cruise ships in the world, they are still cities at sea. And they are well-equipped cities offering a variety of choices with regard to dining, entertainment, and sports activities. The passenger flow is good so that while there are a lot of people aboard, it does not feel overcrowded, especially once you get to know the various alternatives the ship has to offer.
Like her sisters, Mariner is a family-friendly ship with extensive facilities for young people. It is also geared toward physically-active adults. However, that does not mean you have to have kids and be a participatory sports enthusiast to enjoy the ship. While there is not much in the way of enrichment programming, Mariner's entertainment offerings, dining choices and service have earned the ship more mature fans who just want to enjoy a relaxing but entertaining cruise.
Mariner, along with sister Voyager, was selected to popularize the Royal Caribbean name in Asia. As a result, Mariner spent five years cruising in Asian waters. In 2018, Royal Caribbean brought her back to the United States. Along the way, she had an extensive refit in Spain. It added new sports facilities and dining venues and generally refreshed the ship.
