Choosing a ballroom: the questions venues do not volunteer

A venue's capacity is a marketing number. It is usually the largest count the room has ever held, which means theatre seating with nothing else in it: no stage, no dance floor, no registration desk, no photo wall, and no space for anyone to walk.

Your night has all of those. So the first useful question is not how many the room holds. It is how many it holds with your event in it.

The real number

Seated banquet on rounds of ten needs roughly 1.1 to 1.3 square metres a head once service aisles are counted. A stage with an apron in front of it takes another thirty to forty. A dance floor takes about a tenth of a square metre per guest, because not everyone dances at once, and a registration and reception area needs its own footprint outside the room or inside it.

Put those together and a room quoted at 400 often seats 280 comfortably with a proper stage and a floor worth having.

The questions that change a quote

Ceiling height, and where the pillars are. Height decides whether a screen reads from the back row and whether anything can be rigged above the room. Pillars decide how many tables have a view of the stage, and no seating plan recovers a table sitting behind one.

Rigging points, their load limits, and what they cost. Some ballrooms allow nothing overhead. Some allow it only through the in-house supplier. Both answers are fine, and both change the design, which is why it is a question for week one rather than week six.

The load-in route. Lift dimensions, loading bay access hours, whether there is a ramp or a set of steps, how far the bay is from the room. A stage that has to come up in a passenger lift is a different build from one that rolls in off a dock.

What the AV package contains, by name. "AV included" usually means a house sound system, a screen and two microphones. It rarely means show lighting, a switcher, a backline for a band, or an operator sitting at a desk all night. Ask for the list. Then ask whether bringing an outside supplier attracts a fee.

What time the kitchen closes, and what overtime costs. Both are numbers the venue knows precisely and quotes vaguely. They decide whether a programme that runs twenty minutes long is an inconvenience or an invoice.

Ask for the capacity with a stage and a dance floor already in the room. It is the one question that reprices everything.

Look at the room the way your guests will

Site visits usually happen in an empty, brightly lit ballroom at eleven in the morning, which tells you almost nothing about the night. Stand where the furthest table will be and look at where the screen will go. Walk the route from the lift to the registration desk. Find the toilets from the far corner. Ask where the service doors are, because that is where staff will move all evening.

Then ask for photographs of the room set for a dinner rather than for a wedding. Weddings are lit differently and laid out differently, and a ballroom photographed for one can look like a completely different space.
