A poster with only a QR code can leave someone interested in an activity but unable to reserve a place. An alternative route is useful only if it reaches the same booking process and receives the same updates.
Choose one contact method the organising group can reliably manage, such as a staffed phone period or an in-person desk. Say when it is available and what information a person needs to provide. Avoid advertising an unattended number as continuous support.
- Ask the volunteer to enter the booking into the same attendance list used by the online form.
- Confirm the person’s preferred way to receive a cancellation or change.
- Explain how they can cancel their place without using the online form.
- Check that the confirmation contains the date, location and any agreed access arrangements.
Test with a fictional booking before opening registration. Can the volunteer find it later without asking for information the online route never required? Can they correct an error without creating a second entry?
Do not make the offline route depend on a participant borrowing somebody else’s account. The organiser should own the administrative step.
A useful measure of success is simple: whichever route someone uses, they receive a clear confirmation and can change their plans without starting the conversation from the beginning.
