Hey there, Elizabeth!
A warm welcome to planDisney. Thanks for stopping by with your great question about
Walt Disney World Resort theme park rules and regulations.
As someone who always visits the Walt Disney World Resort theme parks with a backpack, I am thrilled to answer your question!
Elizabeth, backpacks of all styles, shapes, and brands are allowed in Magic Kingdom Park. However, your backpack (with or without wheels) cannot be larger than 24 inches long, by 15 inches wide, by 18 inches high (61 cm x 38 cm x 46 cm). Please keep in mind that loose or dry ice is not permitted in any backpack. Additionally, please be sure that your backpack does not have any inappropriate imagery or wording on it.
Please keep in mind that all backpacks are subject to security screening, Elizabeth. I encourage you to
review all Walt Disney World Resort theme park rules in advance of your vacation by visiting this link.
I hope this helps you, Elizabeth. If you have any other questions, please visit planDisney again. We are always hEAR to help you!
Wishing you a Magical Vacation,
Priscila
