Everything is Disney
And what's the most important thing a Cast Member has to do? Stay in character, of course. If you're playing a Disney character, that character's world becomes your world. You're not allowed to make references to any pop culture that exists outside of the Disney universe. From the moment you don the costume to the moment you take it off, you can't talk about anything that Snow White, Peter Pan, or whomever you're playing wouldn't know about—whether that's the latest iPhone or the Harry Potter park just across Orlando. Cast members interact with hundreds of people per day, so make sure you avoid these rude habits when you visit.
Just like you have to be 44 inches tall to ride Space Mountain, you have to be a certain height to portray certain Disney roles. Most notably, anyone aspiring to play a Disney princess—yes, any princess—must be between 5'4″ and 5'8″. If you're shorter, between 4'11" and 5'2″, you can play other characters, including Alice from Alice in Wonderland and Wendy from Peter Pan. This is the longest ride in Disney World.
Looking the part
From hair to fingernails, Disney has lots of requirements for the physical appearances of their employees. Women's hair needs to be in a "classic" style and a natural-looking color. Women actually can have highlights, but they must be "subtle, well-blended, and be over the entire head," according to Disney's career site. As for men, their hair can't cover their ears or be long enough to reach their collars. Men are allowed to have facial hair, but it must be neat, and it can't be longer than a quarter of an inch.
There are also very specific fingernail rules for anyone working in food or merchandise. Your fingernails can't extend beyond your fingertips, and you can't wear nail polish or fake nails. Surprisingly, you can actually have a tattoo—but it has to be completely covered, whether by clothing or opaque makeup. And here's more about what it's really like to play a princess at Walt Disney World.
