Hi, Marlana! On a trip we took in June, I had my husband keep track of how much we spent on meals for our family of four (2 adults, 2 kids.) Our usual day was a quick breakfast at our food court, one table service meal, one quick service meal and a snack or 2 each day per person. On average, we spent between $150 - $175 per day total for our family. This did not include any fancy desserts or alcoholic beverages, so you might want to add a bit more if you enjoy drinks or desserts with your meals.
With a budget of $200 per day, you should be just fine. If you have some specific restaurants you are planning to visit, you can go to
www.allears.net and click on DINING and select your restaurants. Each restaurant is listed with menus and pricing so you can get an idea of what you will be spending.
Hope you have a great trip to WDW!
