Yes, Disney World actively encourages guests to bring their own refillable water bottles into the theme parks as part of their sustainability and wellness initiatives. The only restriction is that the bottles cannot be made of glass, for safety reasons. In 2026, Disney has significantly expanded the number of "Water Bottle Refill Stations" located near restrooms and in the queues of newer attractions like TRON Lightcycle / Run and Guardians of the Galaxy: Cosmic Rewind. If you cannot find a dedicated station, you can go to any Quick Service restaurant and request a cup of ice water for free, which you can then pour into your bottle. It is important to distinguish these from the "Resort Refillable Mugs," which are purchased for a flat fee and allow for unlimited soda, coffee, and tea at Disney hotels, but do not provide free soda refills inside the theme parks. Bringing a high-quality insulated bottle is a peer-to-peer "must" to stay hydrated in the 90°F Florida humidity while saving $5 per bottle on concession prices.
