I'm going to do fewer dinner ADRs for our family. They were difficult for us because we would have to leave park, take a shower (it was June), take nap, wake everyone up, get ready, get to the restaurant. I never knew what the best time for dinner was. Some days, it was hard to get everyone back out to make a 6pm ADR, but 7pm would have been too late to get back to the hotel and rope drop the next day.
Another thing is that I don't think I'll do any pre-rope drop ADRs because with 3 kids, we never got out early and we felt rushed. For breakfast, I am sticking to late breakfasts.
Here is my tentative plan for next year (kids will be 10,3,3)
Arrival night-Dinner ADR (we drive and get there around 1-2pm) and Fireworks
Day 2-Sleep-in, quick snack in room, brunch ADR, dinner at QS in resort (or order pizza)
Day 3-Rope Drop, Lunch ADR in Park, QS dinner
Day 4-Rope Drop, Lunch ADR in Park QS dinner
Day 5-Rope Drop, Lunch ADR, later dinner ADR
Day 6-Sleep-in (pool), hit park in afternoon/evening only, dinner ADR
Day 7-Sleep-in (pool), hit park in afternoon/evening only, dinner ADR
Day 8-Brunch ADR, Later Dinner ADR
Day 9-No Parks, Dinner ADR
Day 10-No Parks, Departure, Late brunch ADR
We won't get the dining plan, but we do have TiW, for the character meals, breakfast is significantly less expensive, so that is where we do the brunches. Also, with TiW we get a discount at TS and at our resort (AoA) QS...so it makes sense to eat lunch in the park and then eat dinner at the resort.
Of course, for our family, and given that we travel in summer, 3/4 or 1/2 days worked better...we either hit rope drop and stay through lunch/early afternoon OR arrive early afternoon and stay through dinner/fireworks.
