There are codes out there, but it is VERY difficult to find availability for those dates because it is Passover Week and evidently everyone from the Northeast is planning on being at WDW. I booked a package through
AAA several months ago, and so far have been unable to find anything better for my dates. If you are flexible with dates and resorts, you might have some luck.
If you are a AAA member, you can apply a AAA room-only discount by calling Disney, and if you want a package, call AAA. There is a public discount out for free upgrades to tickets (code APV, APF includes dining), and Annual Passholder discounts were released this week, but those only "pay" for a long trip or unless you're staying in a very expensive resort for a short trip. Check out the Mousesavers website for more discount codes (not sure if I'm allowed to post the link).
Good luck!
ETA: Just read your post again and maybe you don't even want to stay on-site at Disney? You can save a few $$ per ticket by purchasing through
Undercover Tourist, they have a site. Also for a room, if you are a nurse, teacher or gov't employee, swan/dolphin offer nice discounts.
