After reading Janns comments (she is the Chair 'man') on the Bulletin Board, I do have sympathy for the club. The only people who offered to run the event are a commercial outfit, and naturally they want/need to make a profit. At past events the entry fee from day visits went straight to the venue, so the only money to run the event came from the hotel based members. Hardly fair.
This event, because of its' unique nature, is always going to be sold out and if the organisation can be achieved by professionals ensuring that it goes well and doesn't tie up volunteers any more than they need to be, then why not?
I doubt I will be going, I can think of better things to do with my money.
