I found this on Mousesavers:
Disney Dining Experience
Florida Residents and Annual Passholders can join the Disney Dining Experience and enjoy discounts of 20% on all food and beverages at most full-service restaurants and lounges in the Walt Disney World Resort theme parks and hotels.
The benefit is valid for a party of up to 10 people. Only one discount card can be used per table. The member must be present and must present the card when ordering.
The Disney Dining Experience membership card is not accepted on holidays, including Mothers Day, Easter Sunday, Independence Day, Thanksgiving Day, Christmas Eve, Christmas Day, New Year's Eve and New Year's Day.
Membership includes complimentary resort and theme park parking for dining, as well as invitations to special member-only events. Members also receive half-price admission to Pleasure Island (member and one guest, excludes special events) and FREE admission to Atlantic Dance Hall on the Boardwalk (member and one guest).
Cost is $85 per year for Florida residents and $60 for Annual and Seasonal Passholders. You can add a second membership for your spouse or partner for $25 more, but if you plan to eat together, this is unnecessary. You must have a valid Florida Driver's License or Florida state-issued ID card with a Florida address, or an Annual or Seasonal Pass, to join this program.
Call (407) 566-5858 (Monday - Friday, 9 am - 6 pm EST) for more information.
