Concentrated load in shared areas
A function compresses a week of ordinary use into a few hours and places it in the parts of the building everybody sees. The entry, the amenities and the car park take almost all of it. On a Monday morning the other occupiers arrive to shared areas in a condition nobody in an office building expects, and the complaint arrives at the committee rather than at the venue.
Treating event nights as a distinct condition rather than a variation of the ordinary week is what makes this manageable. A recovery attendance triggered by the venue's booking calendar addresses the actual problem, and it costs considerably less than lifting the routine frequency across the whole scheme for the sake of a handful of nights each month. Targeted recovery is also far easier to justify to owners than a general uplift.
