Usually we are full enough that a snack is fine for lunch, then use the CS for dinner
You could also schedule a couple of TS where sharing is allowed.
So the schedule could look like:
DHS- Hollywood & Vine breakfast, Sci Fi lunch (everyone share, pay OOP to supplement or for a kids meal/drink), CS dinner
Epcot-snack for breakfast, CS lunch, Chefs de France dinner (everyone share and possible pay OOP to supplement or for a kids meal/drink)
OR you could make the meals more at brunch times...we did this with Tusker House and 1900 PF and just had a granola bar or something for "breakfast", hit the park at rope drop (or AM EMH), had brunch and then later a snack, then a CS dinner
