Hi Regina,
Items that you may not bring into the Theme Parks include, but are not limited to:
Items with wheels, such as wagons, skateboards, scooters, inline skates, shoes with built-in wheels, two-wheeled or three-wheeled conveyances, strollers larger than 36" x 52", suitcases, coolers, or backpacks with or without wheels larger than 24" long x 15" wide x 18" high (coolers required for medication may be stored in a locker or at Guest Relations), and any trailer-like object that is pushed or towed by an ECV wheelchair or stroller. Guests are not permitted to pull items behind them. Any item that requires a Guest to pull it behind them, including a stroller, is not permitted into the Park.
Stroller rentals are available at the Theme Parks. Please go HERE to read more about stroller rentals. I hope this helps!
Have a magical day!
