All things are relative Laverda. There's a big drive here to make the event pay for itself and the organisers will want a premium price for the pitch - a bit like an airport does.
also the preferred supplier (a local company Heron & Brearley) will need to provide the infrastructure that goes with the large tent. That said they don't have a brilliant reputation with local customers and in Ramsey at least, their puns aren't in my view as popular as the independents.
