We're at the traditional point of knowing lots of people are coming without actually KNOWING, i.e. no membership forms received and no hotel rooms booked. If people aren't sure they're members, they can get in touch with us direct, ditto if they're not sure they booked hotel.
Most important of course from our point of view is that we don't have the money - there's lots of stuff waiting in the wings to have money spent on it. If we get the money now we can spend it, if you come as a walkin it will cost you £30 more and we won't get to buy things for James to play with.
