A seating plan at an event can have both pros and cons:
Pros:
Ensures that every guest has a seat: A seating plan ensures that every guest has a designated seat, which means that nobody has to worry about finding a place to sit.
Helps manage the flow of traffic: A seating plan can help to manage the flow of traffic in the venue, ensuring that guests can move around comfortably without overcrowding any particular area.
Helps avoid awkwardness: A seating plan can avoid awkwardness by ensuring that people who are compatible are seated together, and people who may not get along are seated apart.
Helps with catering: A seating plan helps with catering by allowing the caterers to know exactly how many people are sitting at each table, making it easier to serve food and drinks.
