Yes, the Disney Wonder features a dedicated water play area for toddlers and young children called Dory’s Reef. Located on Deck 9 near Mickey’s Pool, this splash pad is inspired by Finding Nemo and is specifically designed for children aged 3 and under who are not yet toilet trained. This is a critical feature because, per US Public Health Service regulations in 2026, children in swim diapers are strictly prohibited from entering the main swimming pools on any cruise ship. Dory's Reef features gentle bubblers, colorful fountains, and soft-surface flooring, providing a safe environment for little ones to cool off. For slightly older children, the Wonder also offers the Mickey’s Slide and the main Goofy’s Pool. In the 2024-2025 dry dock, Disney updated the filtration systems for these splash zones to ensure the highest water quality standards, making it one of the most popular spots for families traveling with "diaper-aged" cruisers on the Wonder’s popular itineraries to Alaska and Australia.
