It's pretty easy if you start on the Adventureland side. The morning crowds run to Fantasyland & Tomorrowland at rope drop, so we go to Adventureland. The early long lines are 7 Dwarfs. Peter Pan & Space Mt. So we avoid those and save them for fastpasses. Generally we get Jungle Cruise, POTC, Splash, Big Thunder Mt., Haunted Mansion, Little Mermaid, & Small World and/or Winnie the Pooh in by noon, without using fastpasses. We never go on early morning magic days since MK gets too crowded early. We're from Pittsburgh, so we don't have any Disney connections. By looping it the way we do there's no unnecessary walking or backtracking. If you know the park and how wait times work by the time of the day, it's doable. Of course, once those noon crowds show up, it's all fastpass attractions and/or shows that are generally short waits. And, like I said before, we go in May and October generally, so the crowds are moderate, but not busy or slow. The WDW parks, and Universal too, are easy to navigate if you're willing to be at the parks at rope drop. Same with AK. When the masses go to Pandora in the morning, we do things like Everest, Dinosaur, etc multiple times since they're all essentially walk ons that early.
