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

Which room information was missing?
When did a booking not match your needs?
What description 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: room capacity labels do not explain usable seating layouts.
2. A mismatched booking reveals which requirements were not visible when selecting a room. Clarify verified capacity, equipment or reservation conditions, rather than assuming booking success means the room suits the intended meeting.
3. Turn the requested improvement into a testable next step. One illustrative action is: add verified layout and equipment descriptions.
