As frequent guests at the S/D I have asked in the past if they took the
AAA card for dining discounts and "in the past" I was told no, however I have read more recent posts about the card being used for dining discounts. I would contact the resorts directly to get a definite answer.
Also try posting your question on the dining board if one of the moderators doesn't move this thread--it does have to do with the S/D "resorts" so the resort board would be an appropriate place however people that have dined at the resorts may be more inclined to check the dining board. If you do call and find out they do take the AAA for any discounts please post to let us know.
The only dining discounts I know of at the S/D are for SPG Gold members with children 9 and under. They eat free only at Gulliver's/Garden Grove and Fresh. Palio was included in this, but has since been closed for renovation.
