We did not go last year, but the third week in April is our usual week, since it is the kids spring break week. In 2004 we got a great discount from the disney visa, it was a new card at the time and offered a 40% discount. But other than that, all we have ever gotten is the
AAA discount. Now some of those years the week was also Easter and other years it was not. Last year easter was very early so by the third week in April they were well into the regular season. I believe that if you go to mousesavers.com there is a page there with historic discounts. You may be able to find out if there was a discount.
