Was in my AAA office today for something else, and looked at the "Disney Month" promos. They were offering $200 pp towards an Adventure, plus a digital picture frame. I don't know if it differs from office to office, but this was on a shiny brochure, so probably good everywhere.
Since we only got $300 on our Costco card, this would have been a better savings for the three of us. But I don't know if the early booking discount would still be available. Oh well. But if someone hasn't booked yet, this is a pretty good deal, imho.
