Although I know that the various AAA regions each operate slightly differently from one another, I do believe most if not all of them offer a no-cost, no-obligation quote service for a Disney vacation. It has been my experience that AAA will be able to offer whatever current promotions are available.
The last time I tried to go through AAA, they quoted me a price on a package that was identical - down to the penny - of what I'd booked myself for an on-property stay. And, considering that the previous year I'd gone through AAA for park tickets, and found the people at the office I worked with utterly incompetent to provide them, I started growing very weary of the marginal benefit AAA provided. Alas.
