If what you're asking is if getting an annual pass prevents you from getting the AAA room discount, I'm almost positive the answer is no. When you book a room through AAA, they won't know (or care, honestly!) whether you have an annual pass or not. I know the annual pass entitles you to some discounts (on the DDE, like someone mentioned earlier, and I think some merchandise) but it doesn't disqualify you for other discounts.
As for whether the annual pass would save you money over buying just regular tickets, you'd have to check the price of current annual passes versus current (or discounted, depending on how you usually buy them) park-hoppers or day tickets or whatever.
If I've misunderstood you or confused you further, I'm so sorry!
