I would say we do more like a third-two thirds, and this is how we do it.
Once the park opens, we head to test track. The crowd splits into three groups. First it splits in half with one half going to Soarin', and the other group heading to Mission: Space and Test Track, later that second group splits.
My mom and I are naturally fast walkers, and we kick it up a notch to try to miss the lines. Usually by the time we get to Test Track, we are close to the front of the group, and we usually just walk right on. After we get out of that we get fastpasses to go on it again.
After doing that, we head to Mission: Space. The longest listed wait time we've ever had for that ride was 15 mintues, and that 15 minutes was more like 5-10. After that, we check the line for Energy. Its usually either letting in, or it's only like a 5 minute wait until they do so, so we ride that.
Once we are done doing that, we head over the The Land. We just get fastpasses for Soarin'. Usually it's for like, 2:45-3, but sometimes it's a busy day, and we get nailed with 5, but mostly it's the first. After that we ride The Land. It's usually about a 5 minute wait. Once we get off of that, we eat a quick breakfast. My mom and I arn't big breakfast eaters, so I usually get like, a yogurt and a juice, and she gets some strawberries or something.

After we eat we watch the Lion King movie.
After that, we head over to the Living Seas. Walk around, see some fish. We usually skip the Crush thing. We've seen it once, and that's enough for us.
After Living seas, it's Honey I Shrunk the Audiance. That's all we really do in that area.
Then it's on to Spaceship Earth. My mom and I love it because it's so relaxing. Nice time to get a nap, seing as how we are both tired from getting up at 6 am. We ride that, then hit both inoventions. The things we really hit in those are the Plastic thing. The Fire house game thing, and the house of the future. We also skim over everything else, spending a few minutes here and there.
Once we are done with that, it's usually around Noon. This is when we head over to Mexico for lunch. After eating we ride the Mexico ride. (Just to laugh at how stupid it is). It's then on to Norway and the Maelstorm. We also walk through the shops there. Its then on to China, Germany, and Italy. The way we walk through the countries, is that we just walk through the shops. It's airconditioned, and there are less people, so that's what we do. By then we are at the American Adventure. (so corny

). We watch the movie there, and walk through the shops. We then spend time in Japan and Morocco. We walk through France, (again going through the shops), the international gateway, United Kingdom, and Canada. We usually see the Canada movie. After that, we go do the Coca-Cola thing, ride Spaceship Earth again, use our Test Track Fastpasses, head over to Mexico so my mom can get a Margarita and I can get a Conga, then depending on what time it is, use our Soarin' fastpasses. By then it's usually about Three, and we've usually done everything we want to do. We don't like, run through the parks or anything. We just plan ahead of time. We know where people are going, and we go the opposite way. We know where we are eating, and when we are going to eat. We just know what we are doing.
