I have used two different agents at our AAA Carolinas agency in Charlotte. They all seem to be very knowledgeable. They send you all the info on the dining plan, (will make ADR's for you), a large 42 page book on the must sees at WDW, luggage tags and a few other things. I book through them to get the AAA parking pass.
We even received a small snowglobe as a thank you gift.
You can deal with any AAA agency not just the one in your area.
Here is their toll free number. 1 800 888-3262
