Haven't read through all the posts, so sorry if any of this was mentioned. My DSis and I went last November and we only spent $30 or less a day on food each. I see you are staying at SSR, which is where we stayed. We did breakfast in the room - took cereal bars, and got a small milk at the gift shop for our morning tea. We did a lot of lunches or dinners at DTD - Wolfgang Puck Express is a great value - reasonable prices, large portions - when we ate there for dinner, we took home leftovers and had them for lunch in our studio the next day. Earl of Sandwich is great too - huge portion for the price you pay and so yummy!
When at the parks, there are lots of spots to buy something cheap to eat if you're not fussy and don't care about having a big sit-down meal.
Epcot was my favourite - went to the Boulangerie in France and got a ham & swiss croissant warmed - cost $3.25 and filled me up. Had bought a bottle of Diet Coke beside Rose & Crown first, and we ate inside the gift shop at the back of France where they have tables set up. Lots of desserts to choose from at the Boulangerie as well for under $3.
At MK my sis loved to just get a large McDonald fries for around $2.50 (you can also get these at all the other parks), and a huge cherry or apple turnover at the Main Street Bakery for under $3 as well.
Now that I'm telling you all this, we pretty much lived off of what you can buy with snack credits for meals!

We did go out for a couple of nice dinners. If you make reservations, we found that a late lunch was usually $10 cheaper than an early dinner if it was available, like at Whispering Canyon Cafe where we had the All You care to Eat Skillet. Same at the Crystal Palace buffet at MK, lunch was cheaper.
We had dinner one night at O'Hana (for my birthday) and one night at Boma, which were both wonderful!
You can check out the dining menus on allears.net and map out prices and places on there to outline a budget with your touring plan as well.
Just know that it can be done and you won't starve!!!
Also, if you have an AP or a DVC membership, make sure you know which places take discounts and use them!
Have a great trip!
