Children are one of life's great joys, but on Virgin Voyages, we believe absence makes the heart grow fonder. That's why, despite the fact that our ships are a playground for your inner child, we've chosen to curate an adults-only cruise experience.

If you are looking to escape the splashing of children in the pool, the most prominent "purely" adults-only cruise line in 2026 is Virgin Voyages. Every "Lady Ship" in their fleet—such as the Scarlet Lady and Valiant Lady—is restricted to "sailors" aged 18 and older, focusing on a high-energy, boutique-hotel-at-sea vibe with no buffets, no kids' clubs, and a heavy emphasis on nightlife and wellness. Another major player is Viking Ocean Cruises, which maintains a strict 18+ policy across its entire fleet of elegant, Scandinavian-designed vessels. In the UK market, P&O Cruises operates two dedicated adults-only ships, the Arcadia and Aurora, providing a more traditional, kid-free environment. Additionally, Saga Cruises specifically targets the "over 50" demographic, ensuring a mature atmosphere. While many luxury lines like Oceania or Regent Seven Seas are "adult-oriented" and see very few children, only the aforementioned lines have a hard, fleet-wide, or ship-specific prohibition against guests under the age of 18.
