Royal Caribbean International’s Oasis-class ships, Oasis of the Seas, Allure of the Seas and the new Harmony of the Seas, struck a chord earlier, greeting each other at sea for the first and possibly only time.

In a meeting of unprecedented proportions, the three record-breaking sisters came together to celebrate the US arrival of Harmony of the Seas on the eve of the ship’s debut in her new permanent homeport of Port Everglades in Fort Lauderdale, Florida.

The Oasis-class ships are architectural and engineering marvels, boasting industry-changing and unexpected on-board experiences.

The newest and youngest of the three ships, Harmony of the Seas, officially claimed the title of world’s largest cruise ship, beating her sisters by a mere foot in length and nearly 1,700 gross registered tons.

The ship features a bold line-up of new thrilling experiences, imaginative dining, unparalleled entertainment and the latest technology, including VOOM, the fastest internet at sea.

Harmony combines the iconic seven neighbourhood concept with some of the most modern and ground-breaking amenities and offerings that will appeal to guests of all ages. From The Ultimate Abyss, a dramatic ten-story tall slide.
