Mistake 1: treating Wheelchair Accessible Seating as a late layer
Accessibility usually fails when tables are technically reachable but not comfortable to approach, turn around, or stay at during service and social movement. Teams often wait until the decorative or final-minute phase to solve a problem that is actually structural.
Mistake 2: splitting revisions from the live plan
Planners and venues need to agree on clearances, route width, restroom access, and whether companion seating changes the assigned capacity around a table. Once that link breaks, accuracy drops fast and staff start improvising.
Mistake 3: finishing without a setup-ready version
A beautiful artifact is not enough if the venue team still has to guess where it goes, how it is read, or which version is final. The final layout should document travel routes, table clearances, and exactly where staff must protect space from last-minute crowding or added furniture.
