Jennifer,
I think it seems like a pretty good plan! You don't waste a ton of time park hopping, but use it when it helps you. Great move!
I also like how you end your vacation at the Magic Kingdom.
And your restaurants all seem like pretty good choices! Lots of yummy stops along the way. I think that you will find
Yak and Yeti to be a surprisingly well matched dinner before that great Cirque show. It matches the shows for combining both the exotic and the rustically elegant. I am embarrassed that I never thought of it as a meal idea before the show. FYI, the duck there is great!
I know some will point out that you are not getting to use many of the Extra Magic Hour perks. That is OK. With small kids they may not have been all that useful anyway.
Now if I can help with any other specific suggestions, let me know! I am glad to fill in some counter service suggestions based on locations.
Have a magical (and delicious) vacation!
