Oasis Class
Radiance Class
The Harmony of the Seas, as part of the Oasis Class, is the world’s largest cruise ship offering an array of features including the Ultimate Abyss slide, distinct neighborhoods, and a variety of entertainment options. On the other hand, the Serenade of the Seas offers panoramic views and amenities such as three pools, a Rock Climbing Wall, a mini-golf course, and the Vitality Spa. While both ships offer a variety of dining options and entertainment, the Harmony of the Seas provides a larger capacity and more unique amenities such as the Zip-line and the Aquatheater. The Serenade of the Seas, on the other hand, offers a more intimate experience with its smaller capacity and a focus on panoramic views and outdoor activities like mini-golf and rock climbing.
