U-Shape Boardroom: as your buyers see it
An 80-place U-shape: rectangular tables ringing an open centre, open at one end toward a presentation stage, the layout most boardrooms and hotel conference rooms actually use.
The open centre is the decision that matters, because it keeps every delegate facing everyone else; that is what makes the shape work for a meeting or a training room where people talk across the gap rather than at a lectern.
Delegate and Host are separate tiers here, since the places at the head of the table are assigned rather than sold.
Try extending one arm of the U to seat more delegates, assigning a Host place at the head, then previewing how a delegate books a seat.
