"Disney's Visa cardholders can get a free Disney Dining Plan for travel dates of 9/2/13 " 9/25/13. You must purchase a package that includes a minimum of 3 nights accommodation at a Disney Resort and a minimum 2-day Base Ticket. If you stay at a Disney Value Resort, the Quick Service Dining Plan is free. If you stay at a Disney Moderate or Deluxe Resort, the Basic Dining is free.
You can also upgrade from the Quick Service to the Basic Dining for an additional $19 per adult per night and $3 per night per child. You can also upgrade from the Basic Dining to the Deluxe Dining for an additional $45 per adult per night and $20 per night per child."
Word on the street is that it will be available to the general public on May 9th. I have not seen if they are going to extend the dates into December (w/ blackouts) like they have in the past.
