Let people decide without pressure
Tell everyone what the activity involves before booking. Ask the operator for an accurate description of the walkway and approach. Give people a private way to say they don't want to participate.
A group outing shouldn't depend on persuading someone to ignore their discomfort.
Confirm the alternative
Ask what a non-participant can do and whether they need a different ticket or guide. Agree on a meeting place and how the group will reconnect. Don't assign the person who opts out to carry everybody's belongings.
Check participation rules directly, including any age or other restrictions relevant to your party.
Keep the rest of the day shared
Plan a meal or another common activity afterwards so the outing still belongs to everyone. Let each participant follow the operator's instructions at the site, including any decision to stop.
The Kakum canopy listing helps you choose a destination, while the park can confirm current options. Record which activity each person has actually chosen before paying.
Rules, fees and opening hours change. Confirm anything that matters before you rely on it.
