In the end I decided not to attend, partly because of cost but also partly because I was rather expecting (hoping) to see a proper timetabled programme of events on the website, but alas there was none, just an appetising list of happenings. Surely, any potential attendees require more detailed information before making an informed decision on whether they will be able to take in all they need to over the course of the weekend or part thereof. As others have remarked, it is an expensive weekend if one factors in the cost of travel and accommodation...
Maybe some thought can be given to the above points for next time?
