If nothing was unclear or difficult, say so. Skip questions about steps you did not experience; use not applicable where appropriate. Which entry requirement was unexpected? Where did you look for restrictions? What should be explained before arrival? 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 discover prohibited-item rules at the entrance. 2. The location people searched reveals whether entry restrictions are explained before arrival or only at the venue. Improve links to current official rules; feedback must not substitute for security instructions. 3. Turn the requested improvement into a testable next step. One illustrative action is: place entry requirements in pre-arrival information.
