we get into the parks for free, all of them except for tokyo since that is technically owned my Oriental Land Company. We get discounts off food and merchandise except for outdoor vending foods. Then we have company D which is the CM store that has lots and lots of theme park merchandise for 50% off or more and they always have a holiday sell were they had an extra twenty to thirty five percent off depending on your CM status. There is also the cast holiday parties that take place over a few different nights were the park is open just for us CMs unless you go to the mix in with regular guests but why bother with that.
I used to get tickets fro free movies when I worked there. (back in the 90's) It was only in the Fall and other "non-peak" times. They showed the movies in the Opera House after DL was closed to the public. But that was long ago. They might do it in one of the theaters in DCA now a days.
