Here's a park that's easier to manage in 1 day. In fact, because it's under heavy construction to add lands themed to Star Wars and Toy Story, until about 2019, you may not feel you get your money's worth.
Remember my advice on making Advance Reservations (tel. 407/939-3463) if you want to eat in the park. The Hollywood Brown Derby is a decent sit-down restaurant.
Head directly to the Twilight Zone Tower of Terror. The high-voltage drop ride is not for the very young or faint of heart. The same goes for the Rock 'n' Roller Coaster, which blends incredible takeoff speed with three inversions. The park is small, so backtracking isn't as much of a concern here. Consider passing up attractions that have long lines, or use Fastpass+ where you can. Lines aren't usually awful at Star Tours, the Indiana Jones Epic Stunt Spectacular, but Toy Story Midway Mania is enormously popular.
Voyage of the Little Mermaid is a must for the young (in years or yearnings); the same goes for Jim Henson's Muppet*Vision 3-D, a truly fun show for all ages.
With luck, you'll make it through most of the above before a late lunch at the 50's Prime Time Café, where the food is so-so, but the experience is . . . well, surreal.
Afterward, try your luck at the family-friendly Toy Story Mania ride.
Check your show schedule for favorites such as Disney Junior—Live on Stage! (which is great for little kids) and Beauty and the Beast. At night, do not miss Fantasmic! or, if it's running the evening spectacular that's projected on the Chinese Theater.
