Once the panel has shared information with the audience it can be beneficial to hold a breakout session during the event. Breakout sessions give people a chance to digest the information as a group and come back with questions or comments for the discussion members. Since you don't hold a breakout session with the entire audience, you'll need multiple separate spaces to function as breakout rooms.
The best panel discussion venues with breakout rooms include hotels, office buildings, coworking spaces, and business event centers. These venues all have multiple spaces available for rent. You'll need a main conference room
, auditorium, or other space for the panel discussion. Yet there also needs to be several separate meeting rooms, offices, or classrooms for the breakout sessions. You can also host these kinds of panel discussions at a university, library, museums, or other educational institution with multiple event spaces.
