I haven't seen the gold leaf info on their website, I heard about it from someone who had used it previously. Bdcp is right, you do need to eat all your meals, or at least the ones on the plan, at SOG, and you do waste time going back and forth. I used the plan because my kids wanted to go to a park in the morning, go back and change to swim suits, and hit a waterpark in the afternoon. Maybe at a Disney resort with more frequent buses this would be doable, it's not doable at SOG. We were spending way to much time waiting for buses and it always seemed that we had just missed one.
The walk to Poly isn't bad but it depends on your kids. I saw many parents pushing strollers on the path. I had the drama queen with me and her royal majesty does NOT appreciate being asked to walk! If we caught the shuttle it was all right, otherwise she was impossible. Her twin didn't mind the walk at all.
