Have just completed an large event for a local business in Central Florida, complete with TV personalities. Organized registration, in this case a free event with early-bird registration benefit to manage resources against projected attendees.
One of the challenges in August climate is to ensure sufficient space and where possible temperature control so come rain or shine, guests have a great experience. In this case we had both heat and rain, but there was plenty of room for folks to be comfortable.
With approx 900 attendees, this was about as big as it gets for most corporate events of this type.
