You do get an app with the pkg, so that helps a little. If you would do the pkg anyway, then it could be worth your 2TS credits. The higher priced dinners are at Tokyo Dining, Tutto, Teppan Edo, Coral Reef, and Chefs, so booking a dinner pkg at one of those would bring the "cost" in line with what you want to make the 2TS worth it. They are all right at the $70 price point.
You could book a lunch at one of the lower priced places and pay OOP if you prefer to use your TS credits on other days.
