Harmony of the Seas
The Oasis sister that added the thrills — Ultimate Abyss and Perfect Storm.
Harmony of the Seas launched in May 2016 as the third Oasis-class ship — the first to add the ten-storey Ultimate Abyss slide, the Perfect Storm trio of waterslides and Splashaway Bay. Same seven neighbourhoods, Central Park and AquaTheater as her sisters, with a serious upgrade for families and thrill-seekers.

Onboard
Standout features, at a glance.
A high-level look. We'll go deeper on any of these — including the shows worth pre-booking — when we speak.
The Ultimate Abyss
The tallest slide at sea — a ten-storey drop from deck 16 down to the Boardwalk. The signature Harmony thrill and still one of the most talked-about features in the fleet.
The Perfect Storm & Splashaway Bay
Three racing waterslides (Cyclone, Typhoon and Supercell) plus Splashaway Bay — a full aqua-play area for younger children with drench buckets and mini slides.
Central Park
An open-air park mid-ship with real trees, boutique shopping, 150 Central Park, Chops Grille and Trellis Bar for live music in the evenings.
AquaTheater & Royal Theater
Outdoor AquaTheater at the stern for high-diving shows, plus the Royal Theater for Broadway-scale productions — Grease sails on Harmony.
Dining variety
150 Central Park, Chops Grille, Jamie's Italian, Izumi, Sabor, Wonderland, Johnny Rockets and Starbucks — plus complimentary Windjammer, Solarium Bistro, Park Café and Sorrento's.
The Boardwalk
Coney Island-inspired neighbourhood at the stern — hand-carved carousel, arcade, Boardwalk Dog House and direct AquaTheater views.
Cabins & where to book
Not all balconies are equal.
Harmony has over 25 stateroom categories across 16 guest decks. As with all Oasis-class, the Central Park and Boardwalk balconies are where the class shines — but not every cabin is equal, and Boardwalk views vary a lot by deck.
We'll steer you clear of the obstructed views, the cabins under the pool deck and the noisy connecting doors — and towards the ones that quietly go for the same money.
Best value balcony
Central Park view balcony, deck 10 or 11 mid-ship
Quiet, leafy, mid-ship for minimal motion — usually priced below an ocean-view balcony on the same deck.
Best for families
Boardwalk balcony, aft-facing on deck 12+
AquaTheater views from your own balcony. Avoid low Boardwalk decks if you're a light sleeper — the carousel and diner are close.
Quiet ocean view
Deck 9 or 10 aft-facing ocean-view balcony
Sunrise over the wake, well away from the pool deck. Our pick for couples on a Harmony sailing.
Suite splurge
Crown Loft Suite, deck 17
Two-storey loft with floor-to-ceiling windows — unique to Oasis-class. Coastal Kitchen access and the suite sun deck included.
