A better idea would be to lock up the back wheels with a bike lock. This way, if a cast member needs to move it, the stroller can be tilted forward and rolled on the front wheels. Also, a thief won't want to draw attention by rolling it away like that.

While actual stroller theft is relatively rare at Disney World, "stroller confusion" is very common. To prevent your stroller from being taken, the most effective method is visual personalization. Attach a bright ribbon, a personalized "license plate," or even a battery-operated string of lights to the handle so it stands out among the hundreds of identical rentals. For actual security, many parents hide an Apple AirTag or similar GPS tracker inside the fabric or a pocket to monitor its location via their phone. Do not use a bicycle lock to tether your stroller to a fixed object like a fence or a lamp post; Disney Cast Members are required to move strollers to keep walkways clear and will cut locks if necessary. If you are truly worried about a high-end stroller, you can use a "stroller lock" that loops through the wheels so it can be rolled/moved by staff but not easily pushed away by a thief. Always take your valuables (wallets, phones, souvenirs) with you when you park it.
