Everything a seating plan needs.
Prismm's export or any spreadsheet (CSV or Excel): households, plus-ones, meals and tables come across, matched by column name.
Start from a template, or upload the floor plan you exported from Prismm (an image or a PDF) and trace it.
Seat families together, keep the exes apart, VIPs at the front, and let auto-seat do the rest.
Each household replies, picks meals and lists allergies; the caterer gets totals.
Escort cards, place cards, table numbers, a seating poster and an A-Z list, in any language.
A QR seat finder for guests, and check-in at the door with the Gala Pass.
Three steps.
Download your guest list and your floor plan (Cvent suggests exporting the reports and floor plans you want to keep) before editing ends.
Upload the guest list; households, meals and tables come across. Check anything that didn't match.
Pick a template, or trace the floor plan you exported, then seat everyone.
