Welcome - great question!
Disney sometimes releases discounts called codes - and these codes can save you big money on rooms at their resorts. There are Annual Passholder codes, referred to as AP codes, codes for Florida residents, and also codes for the general public.
Keep watching this board - there is a thread of people waiting for a May code. If and when a code is released, you can call back Disney and tell them you would like to apply the code (usually a three letter code) to your reservation. Mousesavers.com also posts and explains codes.
Another suggestion is to book with a
travel agent familiar with disney. If a code is released, they will contact disney for you!
