For NGOs: Guests often cannot differentiate between the festival’s staff and the NGOs’ staff. If someone approaches you with a question that is outside your NGO expertise, refer them to the info points on the festival site. Don’t give them information unless you’re 100% sure it’s correct – otherwise it might cause confusion. Festivals should have implemented structures to answer any questions the visitors might have.
For festivals: Tell NGOs where guests can find information (info points, official festival crews, apps, websites, telephone numbers). Creating an FAQ sheet / hand-out guide could come in handy.
