You also get 20% at a lot of places at the dolphin...cabana bar and grill, fresh, picabu, fountain, garden grill, sand trap bar and grill, kimonos, splash grill. So if you are staying in the Boardwalk, Beach Club, or Yachtclub area, there are a lot of discounts next door.
I was using my card in the fall and I guess some things have changed. At restaurants in
DVC resorts, I thought we were getting 20% and we also got discounts at Bongo's Walk up window...but only on weekdays, not on weekends.
If you have a Disney Visa, there are also a lot of dining discounts in the DTD area. I got a discount and WPE and Earl of Sandwich I know.
I just flash both cards every single place a I go and it seems like half the time I get some sort of discount.
