Being we do not have year by year attendance figures for LCA, including number of professionals, it seems we'll have to make rough estimates for this event until we can get exact numbers from LA. Last LCA (2007) the number of delegates in total was around the 800 mark with about 50% being professional. Roughly speaking growth, with the exception of Dunedin 2006 has been around 200 delegates per year. Using those figures it would seem that by 2009 there would be around 1200 delegates or more attending the conference, half those being professional. With that in mind, we would need a venue capable of housing, not necessarily seating around 600 professional delegates.
