Social Tables remains a specialist that still earns its place because event layout problems are real, expensive, and easy to underestimate. If room turns, seating, setup precision, and visual collaboration are central to the event, diagramming is not a nice-to-have. It is operational risk control.
The product is most compelling when it is allowed to be what it is: a setup and space-planning layer. Within that lane, the free and Pro entry points are accessible, and the Premium tier gives larger teams the collaboration, attendee management, and Cvent tie-ins they actually need. Outside that lane, the value gets weaker quickly.
Buy Social Tables when diagramming and room visualization are important enough to justify a dedicated tool. Do not buy it expecting it to replace registration, marketing, or full event operations on its own.
