Best Prismm (AllSeated) Alternatives for Hotels & Multi-Property Portfolios (2026)
Last verified: October 2026Following Cvent's April 2025 acquisition of Prismm (formerly AllSeated), hotel and multi-property management portfolios evaluating event layout software typically compare Visiting Media 3D Event Diagramming (best for hotels and management companies that want interactive 2D/3D diagramming connected directly to TrueTour 360°/3D space tours, AI Staging, and unlimited property users), Cvent Event Diagramming / Social Tables (best for teams standardized on the Cvent Supplier Network), and Tripleseat Floorplans (best for independent restaurants and boutique catering venues).
| Category | Visiting Media | Prismm |
|---|---|---|
| Built for | End-to-end hospitality sales — tours, diagramming, asset library, and distribution in one platform | A spatial event-design point solution, now one product line inside Cvent’s broader event-tech portfolio |
| Diagramming approach | Dedicated Diagrams page, guided 4-step Builder flow, and a Furniture & Decor page tying every diagram to the property’s actual on-site inventory | Cloud-based 3D spatial diagramming and photorealistic walkthroughs, oriented around the event planner’s workspace |
| Sales enablement beyond diagramming | Visiting Media Platform: TrueTour asset library, spatially anchored AI Staging, AI Search Optimization (AEO), engagement analytics, and Marriott CORE / Hyatt CANVAS / IHG brand integrations | No equivalent hospitality asset-management or brand-portal distribution layer — diagramming and spatial design is the standalone module |
| Who it’s built for | The property’s own sales team — selling the space, not just planning inside it | Primarily the meeting/event planner’s workflow, coordinating vendors and layouts |
| Ownership | Independent, purpose-built for hospitality sales | Acquired by Cvent (April 2025) — one product inside a much larger event-management suite |
A great diagram helps plan one event. A platform that sells the property helps close the next hundred.
