Yes, you will undergo a security screening before entering any Disney theme park in 2026. At Walt Disney World (Florida), the process is highly streamlined using advanced metal detectors (Evolv Technology) that allow you to walk through without stopping or removing items from your bag. Security officers only perform a manual bag search if the sensors flag a "prohibited item," such as a large umbrella, certain camera tripods, or glass containers. At Disneyland (California), the process in 2026 is currently evolving; while they are testing similar "walk-through" technology, many entrances still require a manual check where security cast members look through every zipper and pocket of your bags. Regardless of the location, strollers and large items are checked separately. These measures are part of a multi-layered security approach that includes uniformed police, hazard-detection canines, and undercover security to ensure a safe environment for all guests visiting the "Happiest Place on Earth."
