We did the plan last year & loved it too!! But yes, it was a lot of food...at least for us!
We would use the CS credits around 11; snack mid-afternoon sometime & than the TS late...like 7:30 or so. What we found was that usually, on both our CS & TS meals, we would be too full to do dessert so we would take something to go & bring it back to our room. We would than use these as late night snacks or depending on what it was, a small "breakfast".
When I say it was a lot of food, I am referring mostly to the dinners. At the time, our sons were 7 & 9 & for every meal, we could order four appetizers & four main courses & than four desserts. Sometimes, the appetizers were so big that we would be almost full before the main course!!
But, you learn to pick what you want to eat & let the rest go. It really was great & I recommend it!!
