Attending a film festival can be an exciting experience, but the cost can vary greatly depending on several factors. From my research, ticket prices alone can range from around $20 for a single film to $500 or more for a festival pass. Then there's the cost of travel, accommodation, and meals which can add up, especially for festivals in major cities. So, it's safe to say that the total cost could run into the hundreds or even thousands. However, some festivals do offer discounted or free events, so it's worth doing your homework in advance.
