We’re here to make the decision easier for you.

Keep reading for an overview of Symphony of the Seas vs Harmony of the Seas to see which of these Royal Caribbean sister ships appeals more to you.

It’s also labeled as the world’s biggest cruise ship.

Harmony of the Seas, on the other hand, was finished in 2016. While it’s not as big as Symphony of the Seas, it holds roughly the same number of passengers.


One of the most exciting parts of a cruise is choosing where to go! Both ships sail around the Caribbean, with prices ranging between $748 and $1,845 per person.

Symphony of the Seas

When you’re not out exploring a port, you can spend your time playing glow-in-the-dark laser tag, catching waves on the FlowRider® surf simulator, or feeling like a kid again in the Playmakers™ Sports Bar and Arcade.

You can also take in a live Broadway show, like Hairspray. Or, if you prefer a slower pace, book a relaxing spa day.

Harmony of the Seas

Do you have a taste for adventure? Then you’ll love the feeling of the wind in your hair as you zip line nine decks above the boardwalk.

Or, plunge down the tallest water slide at sea, when you go for a ride on the Ultimate Abyss™. And, don’t forget to try your hand at rock climbing while you’re at it.
