No, you are strictly prohibited from locking your stroller to any fixed object (like a fence or post) at Walt Disney World or Disneyland in 2026. This is a vital safety rule; Disney "Cast Members" must be able to move strollers at any time to maintain clear pathways for emergency access or to organize the "Stroller Parking" areas. If you use a bicycle-style cable lock to secure your stroller to a fence, security will likely cut the lock and move the stroller. However, many guests choose to use a "wheel lock"—where the lock prevents the stroller from being rolled but does not attach it to anything—though this still makes it difficult for staff to move. The best advice for 2026 is to remove all valuables (wallets, phones, souvenirs) whenever you leave the stroller unattended and use a distinctive ribbon or tag to help you find it in the sea of similar strollers.
