Disney Wonder completed a two-week refurbishment at Seaspan Victoria Shipyards that introduced the Princess and the Frog-inspired French Quarter Lounge adjacent to Tiana's Place. The Vibe teen club was completely redesigned with a brighter contemporary interior, new coffee bar and updated virtual-reality technology, while Cove Café and the nearby Signals Bar received extensive new décor and furnishings. The project also included scheduled technical maintenance and general refurbishment before Disney Wonder resumed service on September 30. Disney announced these passenger-facing enhancements specifically for their debut on that first post-refit sailing.

Disney Wonder underwent an extensive transformation at Navantia Cádiz that introduced Tiana's Place, Marvel Super Hero Academy, the After Hours adult district, D Lounge, Bibbidi Bobbidi Boutique and Cabanas, while Animator's Palate, Palo and Senses Spa & Salon were substantially renovated. The upper decks were redesigned with AquaLab, the Twist 'n' Spout waterslide and Dory's Reef. The project also included extensive interior renewal, hull work and propulsion-system improvements, plus installation of a roughly 20-foot stern “ducktail” to improve the ship's hydrodynamic performance and stability.
