The perks are pretty grand.
Here's a Disney secret for you: ordinary cast members in the parks make very little money. Oh wait, that's no secret, because it's standard for retail and food service jobs. However, Disney rewards cast members with some pretty fantastic perks, including but not limited to: discounts on all merchandise, free entry to your parks any time, many free tickets and entries for friends and family, food discounts, discounted entries to Disney-owned locations, hotel discounts, cruise discounts, access to special events, and so much more. Whenever Disney opens a new attraction at the parks, they always have a soft opening for cast members only. While I was working at MGM Studios, I went to the cast preview night of The Osborne Family Spectacle of Dancing Lights, where we even got treats and hot chocolate.
