Natalie -- Sounds like you won't have a need for an Annual Pass (unless you plan on going back within the boundaries of one year, in which case you can get two trips out of it), but you can still find hotel discounts!
Disney just released a fun discount where you get a pretty substantial Disney gift card when you book, and you can use that gift card for food, etc.:
