Hi Lisa!
You can find information on
Walt Disney World special offers here at this official website. At the moment, Free Dining packages are being offered for Disney's Visa cardholders for select dates 30 September 2012 - 13 December 2012. Generally speaking, discounts for Disney's Visa cardholders usually become available to the general public, so I would definitely check back soon!
Another good place to check for discounts is the independent website MouseSavers.com. There is a lot of information on that site on how to save money at Walt Disney World, at Disneyland, with Adventures by Disney, and onboard the Disney Cruise Line. They usually have the discount information on their site once Disney announces it. It is the first stop I go to when planning my own Disney vacation.
There are family suites at the All Stars Resort and at the Art of Animation Resort. It is true that not all discounts are available at all resorts. Earlier this year, certain discounts were not available to guests staying at the brand new Art of Animation Resort because that resort was already very popular. However, details can be found on the official website once they are released and usually on MouseSavers as well.
I hope this helps! Please write back with more questions!
