Venues + supporting services, are obnoxiously expensive too. My company works closely with conference organizers, and I've seen a quote that was in the mid-5 figures, for 4 days of internet access (and related network services). This was for data services to meeting rooms + conference wifi for about 5k-7k attendees.
