First thing to acknowledge and understand is that you will not, and cannot, do it all. Its fine to try to do as much as you can, but don't try to force yourself and your family to do more than is possible.
Second thing is to judge for yourself what you want to do. If you walk by something and you think 'hey, that looks cool', then do it. Don't let someone on these boards or in a book tell you what is good and what isn't. Judge it on your own.
You only have one reservation, so thats the only time you absolutely need to be in one place at a given time. Don't make strict schedules for anything else.
Are you staying onsite? If so, take advantage of the morning Extra Magic Hours.
The only advice I would give is to get to parks at opening or before they open. It is always the least busy time of the day, and you can get a lot done before the crowds even get to the park. Especially the kiddie rides, like Peter Pan's Flight, Its A Small World, Snow White, etc.
I saw in your other thread that you weren't sure about SeaWorld. Don't worry, you'll enjoy it. I'm not into animals either, but I always have a great time there. Wonderworks is a tourist trap kind of place, you can hit the whole thing rather quickly.
What is the length of your stay, and how many days are you dedicating to the parks?
