IMHO, Hubby should load up on breakfasts before you leave and you should take advantage of early morning touring. Unless you have young kids who want to enjoy and character breakfast the time is better spent in the parks.
Why can't they do both? I have never understood why a family vacation does not include a compromise so everyone's wants are considered.
OP-the transition times previous posters have suggested are a solution to the breakfast/lunch problem, but you can also take advantage of the resort CS restaurant before you head to the parks. My family is a diverse bunch when it comes to breakfast. My daughter has to have a real meal at breakfast and on vacation, my DH does as well. Me, DSIL and my DGD? Not so much. CS breakfast meals are quick, so it really is not that out of the way to hit the counter service in your resort so you DH can have a hot full breakfast. We do this all the time. Your family stays together, and you all can eat or not, depending on what you prefer.
I also wanted to tell you I get that breakfast thing. When we travel with my DH he wants breakfast. Now at home he never eats in the morning, and on his coffee break the man gets honey buns, coffee cake, donuts, apple fritters,......if it is pastry, he loves it! Vacation? Eggs, bacon, toast, home fries......I booked CLub Level a few times thinking that we could use the lounge for a meal in the morning but each time we had a mutiny after two days. He "needed" real food. LOL! But I'll tell you, because vacation is about family, when he is with us, if he wants breakfast, we get breakfast. The parks will be there when we get there, but there is no way that I would diminish my DH by telling himself IASW matters more than he does. You can make it work and still make sure everyone gets considered.
