My best advice to you is use a TA who specializes in Disney Travel. There are lot of sites like this that offer travel.
I have used the TA from this site for the last 10 years and they have never stirred me wrong. There called Dreams Unilimited. You will be assigned an agent and they will work with you to get a good deal.
I also will tell you to do your homework too, read these boards and understand there are many different ways to save money.
When discounts, codes, pins or AP rates come out I e-mail my agent right away and ask if this is a good deal. She usually get back to me within a couple of hours with the savings. Over the course of time I change my reservation many times. I started out with a room only reservation with a
AAA discount, changed it the other day to a General Public Discount and am still hoping for an Annual Pass Discount.
