Try these links. I didn't look back on them, but hopefully they'll have something in them that you can use.

Oh, and with your kids' ages, I wouldn't do the dining plan. It is really expensive, especially since you are expected to pay the tip in cash. The Disney union was able to get that passed - it can't be used against your dining card anymore. Plus, little kids can't possibly eat all that food, and it's overkill.
Instead, eat cereal and fruit in the room for breakfast. You can have milk in the hotel frig. If you are staying at Disney, you can order food - look up ordering groceries for Disney online - bring some plastic spoons and bowls in your suitcase. If they can eat peanut butter, make peanut butter sandwiches for lunch and pack in sixpack soft coolers. I'd bring an umbrella stroller for the little one and hang all your stuff on it. Even if she's not sitting in it all the time, it will really help you.
Then eat dinner somewhere nice. You will save a ton of money.
Have fun!
