A lot of the time, I really wish that the people who organise these sorts of things would let the "pro's" organise things.
We have five or six really large award shows with OB components in our largest ballroom. Every time, their poducers come in and try and make us re-invent the wheel, and it generally ends up with 15 straight edges and the axis off center. They insist on full broadcast splits, but use a studio engineer, who is not used to the nature of live events (with differing playback levels, odd noises, weird accoustics etc) the list of little niggles that 20 minutes talking to people who do live events day in, day out would solve is insane.
We pull off about a hundred of these award type shows a year - it is our bread and butter, many with more awards, and some that are a fair bit more difficult production wise. We frequently broadcast our events as full web casts, use video conferencing and live streaming to run our event over upwards of 7 live sites, and have even done full live to record "tv-esq" style shows - so we know what we are doing.
Yet the TV crews show up, throw a thousand people at the job, take 5 times as long to build it and often get worse results by applying studio rules to what is really an ENG event.
I gather it is the same over in the 'States with events like the Tony's;
