We loved this article about tips for a fun and effective offsite meeting. It was published by a company called Slido who offers an app that makes surveys for company events.
Break the ice at the meeting by playing the game "two truths and one lie." They suggest using this game as a way to introduce new employees. We think it would be fun to do this for each participant. Perhaps award a prize to the participant who has others selecting the most incorrect responses about themselves, to encourage creativity and healthy competition.
