Need more info as there are a number of variables. Where are your ADRs, how old are the girls, do you drink alcohol or plan on have appetizers at the TS restaurants? Do you plan on eating 3 meals a day at the parks/resorts or eat some of your meals in your room? Are you staying on site? Do you plan on sharing meals? Do you plan on buying souvenirs or snacks? For me I can plan on around $50 per day and that is a moving target but all equals out in the end. I'm a light eater and rarely snack on things like popcorn or sweets between meals, I don't drink soft drinks but do drink a refreshing adult beverage. My days normally look like: A child's meal for breakfast, normally a platter which is around $7.00, I stay in moderate/deluxe resorts so I take it back to the room and make coffee there. For lunch again I normally get a child's meal at QS in the parks but let's say adult so around $10, I drink water so I get the free water you can get at QS (I get those throughout the day while walking around). If I eat at TS I normally get an appetizer and soup or salad, a glass of wine (or two) and maybe dessert. I'm going to go with Brown Derby as an example just because it's a signature restaurant and on the high end of the scale. Crab Cake Appetizer $16, Cobb Salad Appetizer portion $11.00, Wine Flight $14, Dessert $15 = $56. Total for day $77 (rounded and doesn't include tip). The next day I may eat the breakfast and lunch I had the day before but have another QS for supper or maybe grab something around WS in Epcot. Some days for breakfast I may grab a muffin, which is only around $4.
I always treat myself to one expensive something in the parks, usually around $200.
I would suggest you look at the menus before you go and get some idea of what you want to eat and add it all up then budget a little higher for food and then figure out if you are going to spend anything on souvenirs. Don't forget to add those mikey bars and popcorn if that's your thing.
