The Harmony of the Seas is relatively new and has not yet needed a significant refurbishment. She's scheduled for the Royal "Amplified" renovations in February 2026. The next scheduled ship refurbishment will occur in 46143. Harmony of the Seas is set for a Royal Amplified makeover that will bring a Caribbean-inspired pool deck redesign, a refreshed adults-only Solarium, and a host of new culinary and leisure venues. Enhancements include the addition of The Lime & Coconut bar and El Loco Fresh for casual Mexican-style dining, Playmakers Sports Bar & Arcade for games and drinks, and Samba Grill Brazilian Steakhouse for an elevated dinner option. The refurbishment will also introduce new suite offerings such as an Ultimate Family Suite and expand casino facilities — positioned to become the largest Casino Royale in Royal Caribbean’s fleet. These upgrades aim to balance energetic family-friendly spaces with sophisticated entertainment and dining choices, supporting the ship’s dual deployment in European summer and Caribbean winter seasons.
