I second the suggestion of Coral Reef for Lunch or Dinner. We loved Boma for Dinner and have read loads of good things about Breakfast there. The only DHS place I've eaten it is Hollywood and Vine, we did the Fantasmic package there. Consider doing that package if you want to see the show. You restaurant choices are H&V, Mama Melrose and for 2TS credits The Brown Derby.
I'd also suggest Narcoossee's for an excellent meal. We took a 6yo who also loved it, especially being able to see the Electric Water parade. We also were there during Wishes and went out to the deck to see that show too. I suggest this as with the Deluxe plan it would be nice to have at least one Deluxe meal. I'd trade one of the Princess CRT meals for this. Really, your hubby lives with 4 Princesses, don't make him sit through 3 Princess meals at Disney too.
I too am very excited about Crystal Palace this trip. However, twice there and B at 1900 PF gives you 3 Pooh meals. Maybe try the Grand Floridian Cafe for breakfast instead of CP. At least at the GF breakfast you'll also get Mary Poppins, maybe the Mad Hatter. As noted others love Kona and 'Ohana B.
The Plaza is another inside MK option. Don't forget you can also use your credits for CS meals. Often pretty tasty, but simpler, easier and less time consuming. I'd suggest Main Street Bakery for a sandwich and magnificent dessert combination.
Your girls are truly lucky to be able to take this trip!
