Nobody books a venue they have not stood in

A viewing has to be matched against the diary, not the calendar

A venue cannot be shown while it is being used, during a turnaround, or while a marquee is going up. The available windows are a function of what is already booked, which is exactly the information a public page cannot carry. Any answer that commits to a specific time without reading that diary is a promise the coordinator may have to break, and breaking it on a viewing costs the booking.

An empty room shows badly, and that is publishable

A room seen bare, with the house lights on and the tables stacked, persuades nobody - and a room seen dressed for someone else's event persuades everybody. Publishing when the space is typically set up, and whether a dressed viewing can be arranged, turns the visit from an inspection into the thing that closes. Most venues know this and almost none say it on the page.

What to publish so the visit is worth making

Who the visit is with and how long to allow. Whether to bring anyone else - the caterer, a parent, a partner who cannot come twice. Parking and access. Whether the visit is required before a date can be held. Whether a provisional hold survives the viewing. Five facts, and the last two are the ones that decide whether the date is still there afterwards.

Record the enquiry against the date, not just the person

The useful record is who asked, which date or season they have in mind, the rough guest count and what kind of event. That lets the coordinator offer windows that actually exist, and over a season it shows which dates are asked about and not booked - which is the only honest read on whether the venue is losing on availability or on the viewing itself.
