Duffy is a little different in TDS. You'll understand when you get there. It's a good thing.
I understand about wanting to experience the park beyond the attractions. There are a rides worth experiencing because of the Japanese additions. I was glad you had ToT on your list, it has a fabulous per-ride show. I do suggest adding the Mermaid Show in TDS to your list of attractions and getting the sea salt ice cream at the push cart outside of the show.
Oh, counter restaurants in both Disneys have English menus at the register.
The 100% Chocolate Cafe was a family favorite. We randomly pointed at items on the menu and enjoyed everything we picked. They also have a wall of flavored chocolates. I bought rosehip, sea salt and a few other new flavors. I think you can see a few of the choices on the site.
