No, the Marella Explorer (often referred to as Marella Explorer 1) is a family-friendly ship and is not adults-only. As of 2026, it continues to offer extensive amenities for all ages, including the M Club (kids' club), a dedicated children's pool area, and family-oriented entertainment like the "Snack Shack" and Broadway-style shows. This is in contrast to its sister ship, the Marella Explorer 2, which is a strictly adults-only vessel. It is important for travelers to distinguish between the two: Marella Explorer 1 is designed for multi-generational travel with "Family Inside" and "Family Balcony" cabins that sleep up to five people, whereas Marella Explorer 2 focuses on a more sophisticated, child-free environment. If you are looking for an adults-only experience within the Marella fleet in 2026, you should look toward Marella Explorer 2, the newer Marella Voyager, or the Marella Discovery (which transitioned to adults-only in summer 2026).
