The 'Get on the Bus' Facebook contest by Contiki Vacations aimed to increase brand awareness and purchase intent among 18-35 year-olds during peak travel booking season. Participants created virtual tour buses, recruited friends, and campaigned for votes to win a trip worth up to $25,000, resulting in significant engagement with over 10 million estimated online impressions and a lift of 25% in brand mentions. The contest successfully leveraged personalization and social sharing, growing the fan base and enhancing brand sentiment.
