We are a family of 4, so I reckon I can offer something here. And a huuuuge congratulations by the way. I've entered a few times and still not got through so well done. Can't wait to hear about the actual flight.
How much you spend clearly depends on where you eat. If you plan to eat most of your main meals (ie brekky and dinner) outside of the parks, then you can better manage the costs. Eating in the park or at the hotels will add cost.
Outside of the park, you can do both breakfast and dinner for around US$100 easy for the 4 of you. For example, if you eat at Cocos (our favourite), main meals are around $12-$15 each (give or take), soft drinks I think from memory are bottomless. If you go to Denny's it's cheaper and of course Subway, Maccas are around, and there is plenty to eat at the Anaheim Garden Walk.
Eating in the park will be different. At the counter service (ie burgers etc), expect to pay around $40 to $50 for the 4 of you. Sit downs will be more obviously, around $70 or $80 for the 4 of you or more depending where. For example, a character meal (and don't scoff, the teeanagers will appreciate it, they just won't tell their friends
) will cost $100 a sitting because it is over US$20 something a person PLUS TAX. Having ravenous kids, you may not go far between ice creams, or churros or things like that, or even coffees for yourself and they add up. Churros are $3.50ish for example and ice creams aren't cheap. So add another $40 or so just for stuff like that each day.
I'm planning for a trip next year at the moment, and I am planning $200 per day for food on average. This is planning for the highest cost days, so hopefully most days will be cheaper, which gives more spending, but some days will get close to that. Last trip in 2005 we allowed $150 per day for food for the 4 of us and it worked out fine. We like to travel with the mindset that we don't scrimp or worry about money, so buget for the high end, which is why it may seem excessive. but with 4 of you, and teenage kids who like to eat non stop, it's best to plan for the higher side I feel.
Don't forget the tipping, and my estimates include tips. Tipping should add 10-20% eah meal in sitdowns, not counter service, so you need to allow for that. Also Tax. Your final bill will be plus tax, around 8%.
Hope this helps. Churros and sandie could also add some quality here as well.
