A family day, open day or supplier day costs roughly €200 to €300+ per person ex. VAT for 250 to 500 guests. For 500 to 1,000 guests you should count on roughly €175 to €275+ per person. For 1,000 to 2,000 guests you should count on roughly €150 to €250+ per person. For more than 2,000 guests you should count on roughly €100 to €150+ per person. All amounts excluding VAT, including venue, catering, entertainment and production.
A family day or open day is aimed at a broad group including children and partners. The price per person is lower than at an evening party because the programme and the catering level are different.
