We have annual passes, and our boys don't go with us very often( grown up)so we don't go like this any more, but when we take family this is our strategy...
are you staying on site? if so, I would absolutely do the emh MORNING hours. NOT evening hours. You won't believe how much you will get done before noon. just eat a little something before you arrive.
Magic Kingdom® Park extra magic hours
Mornings:
Buzz Lightyear's Space Ranger Spin, Cinderella's Golden Carrousel, Dumbo the Flying Elephant, "it's a small world", The Many Adventures of Winnie the Pooh, Mickey's PhilharMagic, Peter Pan's Flight, Space Mountain®, Stitch's Great Escape!, Tomorrowland® Indy Speedway
we head straight to space mtn, usually ride it twice, hit buzz and mickey's philharmagic, we then head to rope for opening, head right to big thunder usually do it twice, grab a fast pass for splash, ride pirates, then head over to haunted mansion. and splash. these are our most favorites. we usually take a snack break and then start going through each of the areas starting with fantasy land.
lunch at columbia harbor house is pretty good and they have a huge cool upstairs.
another big helpful hint if you can't do emh morning hours, is go to the park 30 min before it opens...but go to the park that had LATE NIGHT EMH PARK HOURS THE NIGHT BEFORE....usually so many people stayed up late at that park last night, that the next morning is so much less crowded.
I have been too many times to count, and we always have been able to finish everything by lunch time that are our must do's.
Also, if you are NOt staying on site, or miss the emh day, on A NON EMH day, get the breakfast res at Crystal Palace we like 815. the park is empty and you will get fabulous pictures in front of the castle before you eat. then be at rope drop by adventureland.
we like to do the long cool attractions after lunch....hall of pres. carousel of progress( is that still available, it was in jan.) people mover. we take the monorail over to Grand floridian, contemp. and poly, just to check out the stores, get a drink and relax in the AC.
then get dinner somewhere ( we always have res.) and head back for night at MK....nothing better than that. parade and fireworks are just wonderful...and we stay till it closes, they have to sweep us out!! usually hubby and I sit on a bench with a coke and snack and just watch the people herd out...the kids eventually appear.!
animal kingdom ...in the summer you must get there the earlier the better. it is so hot and humid there. what we do is DH who can't ride roller coasters, goes to Safari and gets all our fast passes while we ride Everest twice, then head to Safari.
we usually skip river rapids, it is just too short a ride, not worth the wait, unless no wait at all.
dinosaur is great, bird show is fun, lion king show is very good.
grab lunch at leave. your kids may find other things there they would like to do, but that does it for us. you can just go about the park and enjoy it, but it really gets HOT!
studios, if you get there when it opens, the rides can easily be done by lunch,
we go to tower, while someone gets fast passes for rockin roller coaster,
do it next, star tours, the Indiana jones and stunt show, do those early, it gets hot standing in line. we love the great movie ride too, little mermaid and muppets.
lunch at backlot express. come back for fantasmic at night.
Epcot...get there early, head straight to soarin, grab fast pass you will want to do it again...then test track and mission space. that
is it for "rides" but get over to crush early or just before future world closes.
the living seas is a fantastic place, I could spend hours there a beautiful giant aquariam, nice and cool .
also, you must ride up in the ball, but the line gets long...
we love to eat in the " cafeteria" where soarin is, we can easily split things, and lots of room.
the countries opens up at 11a m, that is really fun for me, but my boys could care less. they usually stay up in future world till they are ready to leave for the pool.
we have been to disney quest, but in the summer it has been so crowded in there, we had to leave, if you don't have big crowds it is great fun.
lots of shopping and eating at downtown disney, again, my boys could care less, they skip it.
love La Nouba, even the boys liked it....depends on taste.
love eating at wolfgang pucks express yummmY
on the water parks,,,,we love blizzard beach ! but it can get really crowded. check the closing times...sometimes we go after 3 when the crowds really drop off, but afternoon thunder storms could mess that up. again, we have AP, so we don't care if we only get a couple hours in.
You may want to plan one day where you go there when it opens, leave after lunch and do a park in the late afternoon, the only problem is usually by then, all the fast passes are gone, so you are mostly going just for the park and you will hit some lines, or just plan on this being fireworks, parade, eat dinner at liberty tree or crystal palace and shop evening...again I have to stress Afternoon thunderstorms can really mess this up.( fireworks/parade)
Good luck, have fun, and just remember, it will be HOT, there will be LOTS of people, it will RAIN at some point, but who cares! you are at Disney World, the happiest place on Earth! oh, dont' forget to REST and RE HYDRATE!!!
Be PATIENT and keep your sense of HUMOR
), as he will tell you what rides to do when with the least amount of queing. I have never done this, as i always go for two weeks at a time (being a Brit and all) so take it a more relaxed pace. However that does limit your freedom to do as you like, so its a bit of a balancing act. 
. I will say this again (even though you've probably heard it by now) DON't miss HS (or MGM) it is the highlight of my trip. Without Tower of Terror or Rockin' Rollercoaster my trip would be a wash out. If the park is too small for you, take the rest of the day as a 'relax' and have a swim by the pool! To be honest i like the slow stuff to, so i could easily spend a day.
