Hello and welcome to the Disney Parks Moms Panel!
You are visiting Walt Disney World during a most MAGICAL time of year. The sounds are SPOOKtacular and the sights are BOOtiful! You are going to love this time of year at WDW.
What a great question! This is a tough one. The rules state the following:
"Costumes may not contain sharp objects, pointed objects or materials that may accidentally strike another guest." Upon entrance, a Cast Member will need to decide if your grandson will need to leave his wand behind. Personally, I believe he will be able to keep it with him as I have seen small children with wands that have been purchased inside the parks. You can read more
costume guidelines by clicking on the provided link.
Diane's Tip of the Day: Make sure to stop by The Chapeau, located down Main Street, U.S.A, inside the Magic Kingdom. They have a variety of Mickey EARS to choose from.
Have a MAGICAL day and "SEE YOU REAL SOON!"
