What fits in this room
An exhibition building is bought by the square foot, not the seat. What decides whether your show fits is column spacing, ceiling height and how many trucks can be on the dock at once, so ask Sonoma County Fairgrounds for the hall sheet rather than a capacity number.
- trade shows and exhibitions
Built as a floor rather than a seating plan, which is what an exhibition needs.
- multi-track conferences
The same hall subdivides into tracks once the booths come out.
- career fairs
A booth grid and a single controlled entrance is the whole requirement.
