The European League Against Rheumatism (EULAR) has grown its annual congress attendance from 4000 in 2001 to over 12,000 today during an era of heightened security around the world. The tremendous growth of this event is due to several critical components that you may find instructive: 1) Development of a "delegate loyalty" program strategy for European audiences 2) Building a consistent and permanent industry sponsorship program with pharmaceutical companies. Case studies on the 8th World Congress of the Council on Tall Buildings and Urban Habitat held in Dubai, UAE will also be explored.
