Coming in May

There are a lot of other little tweaks on Harmony of the Seas. Many are in the food and beverage offerings; Wonderland, the playful molecular gastronomy restaurant, will now span two stories, with a bar on the top floor serving creative cocktails and small bites. In addition, the main dining room will have two floors of My Time dining rather than just one, since the eat-when-you-like program has been especially popular with new cruisers and younger travelers.

But those aren't the only changes from the previous ships built in these classes. For example, the popular adults-only lounge, Solarium, is getting an additional 140 seats to meet demand. And the ship's theater will be home to the company's latest Broadway-style show, “Grease,” as well as a new production, "Columbus: The Musical."

But fans of Royal Caribbean’s Oasis and Quantum classes will find their favorite features are all here, too — we can already tell that the atmosphere will be both festive and familiar.
