That would be too much food for my family, but everyone is different. Depending on when your Kona breakfast is, you'll likely not be hungry for a buffet lunch, and if you push that back, then will you be hungry again in time for a full dinner? Even if you share at Kona and The Wave, you're still taking time away from enjoying the park. With a group your size, I would "budget" at least an hour and a half for every meal...that's waiting to be seated, ordering, getting and eating food, and paying. Add to that the time it will take to get to/from each place, and you use about 6 hours of your day in eating. For many people the meals are a part of their vacation and they're okay with that. I just want to be sure you are aware of that.
How are you getting to Captain's Grille for that early breakfast? If any of your family have the buffet there, will they want another buffet type meal at Akershus AND a full meal at Tokyo that evening? It does seem like a lot of food to me.
With 6 nights, you'll each have 6 TS credits to use, and with your arrival/departure plans, you only 5 days you need to plan for. If you want to keep all of your ADRs, plan to use the credits at your buffet places first, then you can allocate the other credits to sharing meals.
Once you have your plans firmly in place, come back with your ADRs and we'll help you figure out where to best use credits and where to pay OOP.
