Hey there, hi there, ho there Angela and welcome to the Disney Parks Moms Panel.
I am so glad you asked this question because little princes need to be comfortable at the place "where dreams come true." Funny enough my sons loved being in the stroller so they did not have to use their legs all day and it gave them a private place to play while I acted as chauffeur.
Walt Disney World Resort Park Rules are very specific about what strollers and other "people movers" are allowed in the theme parks.
Items that are not permitted include wagons (whether you can push or pull them), "stroller wagons," extra large strollers larger than 36" x 52" (92 x 132 cm), and trailer-like objects that are pushed or towed.
Disney Dad Tip: There is so much excitement at the theme parks and kids need to some downtime or playtime.
Tom Sawyer Island,
The Boneyard,
Casey Jr. Splash 'N' Soak Station (bring a swimsuit) and
KidCot Fun Stops are places your son can relax or romp. If you do not want to carry bags around all day then use the
locker rentals available at each theme park.
Angela, please let us know if you have any more questions and enjoy making many Magical Memories.
