Sometimes special room rates are offered for Annual pass holders. They are better than the DC deals, but they are not announced until a few months ahead of time & are not always available. It's best to book any kind of discount while you can & then wait for AP or code rates (for the general public). You can book 2 rooms with just 1 AP, and you can always book the rate when it comes out and then get your pass. You just have to have it for check in.
PAPs with the DC discount are about $500 each. That's a lot, but if you might be able to go back to Disney before July 1, 2004 you'll save on your next trip!
If you're staying 9 nights it's $92 per room per night inc tax. That doesn't sound bad for Summer. It's possible you might be able to book the rooms for less than that if a code comes out. Keep watching the Resorts board & Mousesavers.com for new discounts!
