Well, you're certainly thorough!
In theory you've created a wonderful iternary. But WS is one of those places that you can't "plan" in the same way as the other parks. Often there will be several shows going on in different countries at the same time. Some times you'll be walking through a country and get mesmerized by something you didn't plan for - like the balancing waiters in France or the lady "statue" in Italy or the acrobats in China. WS is my favourite part of WDW and we've been dozen of times. I can honestly say I've never seen all the things you plan to see in one day - especially if you're making a stop at each Kidcot. So my advice is to tour World Showcase with a more "European" relaxed state of mind. Stroll along. Enjoy what you do discover and savour the unexpected. Last year in Morocco while my daughter bought a little book about "Habibi" a camel who wanted to wear slippers, the young clerk in the bazaar told us "Habibi" means "my love", and he went on to tell us a wonderful Moroccan folk tale. That was one of my fondest moments of our last trip.
Also - just a warning - while the "snacking" is a great idea - it's amazing how much money you can spend doing this. Choose wisely.
I'm sorry - I don't mean to rain on your parade, I just don't want you to be disappointed if your itinerary doesn't run like clockwork - but that will be a good thing. The unexpected moments are always the best.
