If nothing was unclear or difficult, say so. Skip questions about steps you did not experience; use not applicable where appropriate.

Which transport detail was missing?
What departure information did you need?
What route explanation would help?

Author notes / illustrative keys where applicable:
1. Use this answer to locate the part of the experience that needs explanation. The example issue to investigate is: attendees cannot find the final shuttle departure time.
2. Departure information needs identify gaps that arrival-only guidance misses, such as published transport options or service times. Link verified sources and relevant limitations, rather than promising transport availability or journey duration.
3. Turn the requested improvement into a testable next step. One illustrative action is: publish verified service times and alternatives.
