Interactive corporate entertainment can be great fun. For example, murder mysteries, treasure hunts, and casino nights are good options. If you'd like something a bit more tame, wine and cheese tastings, cooking classes, and the like can also be enjoyable.
If you opt for interactive entertainment for your corporate event, consult with your performer on ways to make the fun accessible to everyone. Some people will be a little reluctant to get involved, so it's up to the entertainer to put them at ease.
