Disneyland and Walt Disney World primarily sell Dasani water because of a multi-decade, exclusive "strategic alliance" between The Walt Disney Company and The Coca-Cola Company. This partnership, which has existed in various forms since Disneyland opened in 1955, grants Coca-Cola the "exclusive pouring rights" for all non-alcoholic beverages within the parks and resorts. In exchange for significant financial sponsorship and marketing support, Disney agrees to sell only Coca-Cola-owned brands, which includes Dasani bottled water, Sprite, and various Fanta flavors. While some guests in 2026 criticize the "salty" taste profile of Dasani (which contains added minerals for flavor), the exclusivity is a cornerstone of Disney's business model. To provide an alternative, Disney offers free cups of filtered ice water at all Quick Service locations, and many newer areas of the parks have been outfitted with "refillable bottle stations" to accommodate guests who prefer their own filtered water over the bottled Dasani. This partnership is one of the most successful and longest-running corporate sponsorships in the global entertainment industry.
