When it launched in 2000 as the second ship in Royal Caribbean’s Voyager class, Explorer of the Seas was the largest passenger ship in the world. Over the next two decades, the cruise line would debut ever-larger classes of ships and Explorer began to feel somewhat dated. But several refurbishments later — including the long-awaited addition of a pair of Perfect Storm racer waterslides 2023 — and this 3,286-guest ship now features a range of fun activities that make it feel more up-to-date than you might expect. These include an ice-skating rink, FlowRider surf simulator, Rock Climbing Wall, mini golf course, pickleball, musical productions, and live game shows. Explorer of the Seas may not have benefitted from a full pre-pandemic “Amplification” like its sibling Voyager-class ships, Voyager of the Seas, Mariner of the Seas, and Navigator of the Seas, but there’s plenty for active couples and families to love.
