I would get there before the park opens, know what rides I want to do and what order do to them.
Have lunch at the castle (which is undoubtedly booked on that date by now) second choice would be Grand Floridian Cafe for two young girls.
In the afternoon I'd do less popular rides, watch the parade, use fastpasses for favorite rides and shop.
I'd have dinner at Chef Mickey or the castle, if I didn't get lunch (both again might be booked by now) then I'd choose either Crystal Palace if they wanted or the Plaza Restaurant.
In the evening I'm not sure, the schedule says both Spectromagic and Wishes are at 9, I would think Spectro is 9 & 11 and Wishes 10. So what I would do THEN, is do rides during the first parade, see Wishes at 10, grab my spot for the parade and get something yummy from the bakery, watch Spectro at 11 and end a wonderful day at MK!!!
