Adults have autonomy. Your camp should not treat them as children who need permission for every ordinary choice. At the same time, organized activities need clear accountability.
Explain when a guest is in a guided activity and when they are using personal time. For guided trips, use the agreed roster, route, check-in, and return process. A guest leaving the group should tell the designated leader so the safety plan can be updated.
For independent time, provide practical information about boundaries, local hazards, return expectations where relevant, and emergency contacts. Do not imply you are supervising someone when you are not.
If a person misses an expected check-in and there is a safety concern, follow a prompt, risk-based response. Do not use adult status as a reason to ignore a credible emergency.
Set conduct rules for shared spaces: harassment, noise, property, privacy, and visitors. Enforce them consistently and through a fair process.
Do not use financial pressure or group loyalty to keep someone in an activity they wish to leave. Arrange a safe exit or alternative within the program's duties.
Your task: Mark the boundary between guided participation and independent time in both the schedule and guest information.
