I actually tracked everything while I was there. I brought a lot of snacks that I could easily measure, like 94% popcorn, Fiber One bars, etc. I did eat Lunch and Dinner every day either in the parks or one night off site. I stuck to Kids Meals and went with ones I could easily calculate, i.e. Spaghetti, 1/2 wrap, etc. Kids meal sides have grapes and something else healthy (I am blanking at the moment, I think baby carrots) as choices and you can get a lowfat milk too as the drink choice. It worked out well...I did treat myself a few times, at DTD split a Ghiradelli sundae with my sister...my 1/2 was 11 pts, but well worth it!!!
We did one character meal, the Norway princess breakfast at Epcot...I ate 17points at that one meal, but I planned for it...
Good luck to you, and have a great trip!
