Regarding Brad using the word "revenues", I may be wrong, but I assumed that he meant profits. Some folks confound the two, sometimes on purpose, other times because they don't think it through. Though the revenues from events may be considerable, the cost of goods sold (what they have to pay the resorts, guest speakers, for staff transportation, etc.) is probably as well. If there is much of a profit margin, I'd be surprised, though I have no idea what they're charging these days. Based on the prices I saw when I was a rater, I doubt they netted enough to make it worthwhile as a profit center, though probably great fun for the staff.
