About this data
This page is part of the EventDiagram venue registry — floor-plan data published for event planners, vendors, and the venue itself. This record was compiled from the venue's public materials and has not yet been claimed by the venue. Room dimensions here come from the venue's own published materials. We have not yet traced these rooms to their real perimeter or recorded independent scale checks, so shapes are shown as simple rectangles at the published dimensions. Software assists the tracing; a person reviews every plan against its source before it appears here. Capacity figures are only ever the venue's own published numbers — we never estimate them. Full details in how we measure venues.
