Royal Caribbean's Harmony of the Seas has come out of a 44-day drydock at the Navantia shipyard in Cadiz, Spain, with notably more places to sleep. The refit wrapped up in May 2026 and was carried out by marine interiors specialist Almaco Group.
The headline change is a new accommodation block built into the forward section of the ship: seven panoramic suites and 21 staterooms. On top of that, parts of the two-deck Wonderland restaurant were converted into 29 additional staterooms, taking the total new cabins to 57. With cabins going in above the Music Hall, the team also fitted a noise-reduction ceiling to keep things quiet for guests upstairs.
The scale of the operation was substantial. Preparation ran for around seven months before the ship even arrived, covering design, engineering, procurement and coordination between Royal Caribbean, the shipyard and multiple contractors. During the drydock itself, Almaco had as many as 240 people on site and shipped in roughly 86 TEUs of material to Cadiz.
For anyone eyeing a Harmony sailing, the practical upshot is more cabin choice, particularly at the premium end. A fresh block of forward-facing panoramic suites is a meaningful addition to an Oasis-class ship that already carries thousands of passengers, and converting restaurant space suggests Royal Caribbean is rethinking how much of the ship is dedicated to dining versus sleeping. Cabin categories and inventory are worth checking when the refreshed deck plans filter through to the booking system, as new cabin types sometimes launch with introductory fares.
Harmony of the Seas is one of the largest cruise ships in the world, known for its seven-neighbourhood layout, slides, the Ultimate Abyss drop slide and a full Broadway-style entertainment programme. Post-refit, expect the same big-ship energy with slightly more variety in accommodation.
