We've never done this before, but the plan for an upcoming visit is:

Hollywood Studios at open - ride Rockin Roller Coaster and Tower of Terror 1x-2x each. Maybe Star Tours too.
Animal Kingdom late morning - Fastpasses (starting around noon?) for Expedition Everest, Primeval Whirl and Kilimanjaro Safaris.
Epcot late afternoon/evening for the Food and Wine Festival.

What do you think? Any recommendations?
