You can definitely NOT spend $80-$100 for two people per day. If you eat a breakfast sandwich at the resort, it's like $5-$7. Or bring your own cereal and buy milk. For lunch, DD15 and I shared a combo at Regal Eagle in Epcot (remember Americans like big portions so you can also share some stuff). Most days, we bought sandwiches and fruit from the grab-n-go counter ($9) and brought to the parks. Then we would buy an ice cream or treat at the parks. Dinner will run you a bit more but do some research.
