How did this end up Darren ?
I budget for an amount of cancellations over December - venues can often be a little over ambitious - however have found this year to beat every other year for cancellations - including 3 on NYE.
I have took most of it on the chin, however with one venue I am 'in negotiations' as my NYE has a 2 month cancellation period and they only cancelled on Monday. On top of that I have nearly £8k of overdue invoices from them.
