Yes, you can bring your own bottled drinks into Disney theme parks in 2026, but they must follow high-fidelity safety and security guidelines. The primary rule is that glass containers are strictly prohibited (with the exception of small baby food jars). You are welcome to bring plastic bottles of water, soda, or juice, as well as high-fidelity reusable water bottles like Hydro Flasks or Stanleys. For 2026 visitors, it is a high-fidelity "pro-tip" to bring a refillable bottle, as both Walt Disney World and Disneyland offer numerous "High-Fidelity" water bottle refill stations throughout the parks. Additionally, alcoholic beverages from the outside are not allowed inside the parks. All bags and coolers are subject to high-fidelity security screening; coolers must be "soft-sided" and no larger than 24" long x 15" wide x 18" high. By bringing your own high-fidelity beverages, you can save a significant amount of money and stay hydrated while navigating the long queues and warm weather typical of a Disney vacation.
