At Disney World and Disneyland in 2026, pregnant guests are advised to avoid any attractions that feature sudden drops, high speeds, or jarring movements. These typically include all "mountains" (Space Mountain, Big Thunder Mountain, Tiana's Bayou Adventure), as well as TRON Lightcycle / Run, Guardians of the Galaxy: Cosmic Rewind, and Star Wars: Rise of the Resistance. Other restricted rides include The Twilight Zone Tower of Terror, Slinky Dog Dash, and Mission: SPACE. Even relatively "slow" rides with high-intensity vibration, like the Kilimanjaro Safaris in Animal Kingdom, carry a pregnancy advisory. Disney provides a comprehensive "Expectant Mothers" guide on their app, but as a rule of thumb: if a ride has a height requirement, it almost certainly has a pregnancy advisory. Most "slow" dark rides like it's a small world are perfectly safe.
