Greetings Lisa! Welcome to planDisney! Your trip is so close, and you must be getting so excited. You're in the home stretch now, so let's get right to it.
I'm not sure if you're planning on bringing your own stroller or taking advantage of
Stroller Rentals in the
Disney Theme Parks, but it sounds like you're brainstorming ways to keep your property safe while unattended. I took a look at the
Walt Disney World Resort Property Rules, and I didn't see Air Tags, Air Tag holders or small screwdrivers on the prohibited items list, so based on that, they seem to be allowed. That being said, all bags are subject to search, and final decisions on whether an item is allowed is always at the discretion of security. Policies are in place for the safety and comfort of Guests and Cast Members, and anything that security feels could impede this may not be allowed, whether it's on the prohibited list or not. I also want to let you know that Disney isn't responsible for the loss or damage of belongings, so it's best to avoid leaving anything unattended, if possible. I know the stroller itself won't be able to go on attractions, so consider removing valuables prior to parking the stroller, as a best practice.
I have some other ideas for you to help ensure your stroller doesn't get mixed up with someone else's. Similar to luggage, I recommend tying something recognizable to it like a ribbon or bandana to make it easy for you to spot in a sea of strollers. Also, consider tagging it with your name and phone number so it can easily find its way back to you if it gets inadvertently carried away. Speaking of carried away, Cast Members can sometimes move strollers around for traffic flow, so if you return to find your stroller missing, ask a nearby Cast Member if it has been moved.
Another idea to keep your belongings safe while enjoying your day is to rent a locker.
Locker Rentals are available at each Disney Theme Park, and I'm a big fan of them. I find my days are much more enjoyable the less I'm carrying around. Plus, it gives me a place to stow anything extra that finds its way to me throughout the day, like merch. Just be sure to empty it before heading out of the park for the day. I almost forgot my jacket once. Oops!
Lisa, I hope this has been helpful to you. Have a great trip, and visit us again with any other planning questions.
Let your dreams guide you!
