The problem is that of nine people who went from our village today, two adults were season ticket holders, four adults paid £5 each, one under sixteen and an under ten went free and the other under ten was on a free season ticket.
So of nine people the actual outlay on the day was £20 (plus the two already paid for season tickets).
Now I'm not in marketing (I'm actually a geologist) so I really hope that there is some clever plan behind this.
