Found on: Quantum of the Seas and Anthem of the Seas, Royal Caribbean

Once you discover the comforts of this atrium-like, adults-only spot at the bow of Deck 13, you’ll never want to leave. Why would you? It’s an oasis of palm trees, cascading pools, hot tubs, cozy daybeds, and panoramic views.

Found on: Eurodam and Nieuw Amsterdam, Holland America Line

The entire family can enjoy this sleek, contemporary space that features a lap pool, a trio of hot tubs, private cabanas, and lighted dancing fountains.

Found on: Europa 2, Hapag-Lloyd Cruises

Encircled by a promenade deck, this elegant space has a pool and whirlpool — and a curved glass magrodome that conveniently slides into place just as raindrops start to fall or the chill settles in.

Found on: Solstice-Class Ships, Celebrity Cruises

For a moment of Zen, it’s hard to beat this adults-only space. In addition to a lap pool and cushioned loungers, there are two heated whirlpools — all enclosed by glass walls and a roof for spectacular views.

Found on: Breakaway-Class Ships, Norwegian Cruise Line

If you love a big ship but long to sit by a private pool, you can upgrade to the Haven, a “ship within a ship” on Norwegian's Breakaway, Getaway, and Escape. Its serene courtyard is covered for indoor dips. Bonus: It's serviced by attentive staff that you don’t have to share with the rest of the ship.

Found on: Spirit-Class Ships, Carnival Cruise Line

With a retractable glass roof overhead, the variously named main pools — one of the two mid-ship Lido Deck pools on Carnival's Pride, Legend, and Miracle — are ready for whatever weather Mother Nature tosses their way.

Found on: MSC Divina, MSC Cruises

Sometimes an enclosed, adults-only space can make all the difference on a large, family-friendly ship like the MSC Divina. That spot is the One, which features a peacefully serene pool and two uncrowded hot tubs, accessible only to MSC Yacht Club members. The other all-weather alternative: Le Sirène Pool — with a retractable roof — but you’ll share the space with kids (and you won’t be shielded from the noise from the very lively Aqua Park).

Found on: Queen Mary 2, Cunard Line

When things get a little blustery on a transatlantic voyage, guests aboard Queen Mary 2 can head to this petite oasis with its teak-wood accented pool, pair of hot tubs, and green-striped loungers reminiscent of the lawn chairs in London’s Hyde Park.

Found on: Diamond Princess and Sapphire Princess, Princess Cruises

The two-level Conservatory Pool has mosaic-tiled columns and a sliding glass roof to banish even the most unpredictable of elements: cold, rain, snow. Star, Grand, Royal, Regal and Golden Princess feature similarly covered areas under the name the Calypso Pool.

Found on: Brilliance of the Seas, Royal Caribbean

For a cozy dip in a setting inspired by an African watering hole, head to the adults-only Solarium Pool on Deck 11, with a tranquil, elephant sculpture-lined pool, bubbling hot tubs, and a bar.
