"The awards banquet, which cost $461,745, was held at the Grand Hyatt, which bills itself as "one of the most magnificent" hotels in the nation's capital. According to the report, the agency chose that site because it was the only hotel available on Nov. 19, 2003, the agency's second anniversary. It also was one of the few places that could accommodate about 600 honorees and as many guests."
$461,745 divided by 1200 people = $384.78 per person.
Note, that is, as I said, per person. Considering that we are talking about TSA policy makers here, I imagine that there were considerably fewer heads.
