We tend to arrive at rope drop, do the headliners in 2 or 3 adjacent "lands," and then as the lines get long a couple of hours later, work our way back through those same lands, hitting the "anytime" attractions of interest. After lunch, we go back to the resort, rest up, swim, etc. until about 4pm, when we return to the park to finish off the lands we skipped in the morning, using FP+ for headliners.
The only park we do differently is MK, which really requires at least a day and a half (ideally, two rope drops) to get to all the headliners.
E.g.:
MK Day 1, morning (Adventureland, Frontierland, part of Liberty Square): Rope drop Big Thunder, Splash, Haunted Mansion, Pirates and/or Jungle Cruise. Then do, as time allows, attractions like Swiss Family Treehouse, Magic Carpets of Aladdin, Enchanted Tiki Room, and Country Bear Jamboree. Have lunch and go back to the resort for a few hours.
MK Day 1, evening (Tomorrowland, part of Fantasyland): Return to the park with FP+ for Space Mountain, Buzz Lightyear and 7DMT. In between, have dinner and hit Monsters Laugh Floor, Carousel of Progress, Peoplemover, Mad Tea Party, Philharmagic, Carrousel, Little Mermaid, etc.
MK Day 2, morning or evening: At rope drop or with FP+, finish Fantasyland (e.g., FP+ for Peter Pan, Pooh, 7DMT again?). Visit desired character M&Gs and/or spend time on Tom Sawyer Island. See parade and/or fireworks if desired.
