We usually budget $100 a day for 5 of us,(dh, me, ds13,dd15,dd2) We have never gone over that except when we have decided to do one ts or character meal. We all have atleast an icecream a day...share a popcorn...one or two more snacks...We save $ buy eating in the room for breakfast..i bring muffins, pop tarts, cereal,etc. All lunch and dinners are at cs in the parks. We also save $ by bringing water into the parks..we save $25 atleast a day doing this. If we ate cs breakfast it could easily be done for us $25 or less. So when I say that $1oo covers us I mean we usually only spend around $70. We tend to snack more at EPCOT so that is the one day we reach $100. LOOK at the menus on the site, figure out what you think each person might get and figure it up! You and your dd could definetly share some meals they tend to give you alot. I also bring some snacks from home too to tide them over when standing in line this helps w/ ordering too much just because your starving.
