TL;DR
Choose one must-meet character, one backup, and one time window. Treat the rest as bonus, especially with kids.
The practical problem
Epic Universe has enough headline rides, food, lands, and photo moments that character hunting can turn into its own itinerary. That is fine if it is the point. It is rough if it steals the day by accident.
The family rule
Let each kid pick one character or land moment that matters. Not five. One. That keeps the plan from becoming a scavenger hunt.
What I would do
Check the app day-of, build a character window around the land you are already visiting, and keep one backup if the timing shifts.
Who can ignore this
If your group is ride-first or adult-only and character photos are just nice-to-have, do not plan the day around this. Catch what you happen to see.
Use this quick checklist
- Choose one must-meet
- Choose one backup
- Check the app day-of
- Do not cross the park for every meet
- Treat surprise meets as bonus
