Room Set-up Examples
Conference and Hollow Square
Appropriate for interactive discussions and note-taking sessions for fewer than 25 people. Many hotels have elegant "boardrooms" for 10 to 20 people, equipped with full audiovisual capabilities, a writing board, cork board and a flip chart.
Room Set-up Examples
E-Shape, U-Shape and T-Shape
Appropriate for groups of fewer than 40 people. These are best for interaction with a leader seated at the head of the setup. Audiovisual is usually best set up at the open end of the seating.
