Disney Don'ts: Follow These Rules and Your Visit Will Be Magical

Mouse ears are fine, especially the pink sparkly kind. But Disney forbids grown-ups from wearing masks while in Disney Parks while also requiring any kids with masks to make sure they can still see.

Here's the official rule: "Masks may not be worn by any Guests ages 14 or older (unless required for medical purposes). When worn by younger Guests, masks must provide unobstructed peripheral vision at all times with openings that allow the eyes to be fully seen."
