Re: Where does the money go?
The seminar fees attempt to cover the expenses for the event -- the honorarium for the shihans and guest instructors, facility rental, mat rental, air-land transportation for the shihan and guest instructors, accommodations for same, refreshments at the event, etc. The fees do not cover any of the efforts of the members of the hosting organization(s) for sponsoring, advertising and running the event -- usually, if they are lucky, the seminar will break even. The bigger ones usually come out a little ahead at the end, all of which gets plowed back into sponsoring their next annual event. I know of at least one regional summer camp that frequently has been run "in the red," supported by the accrual of past years dues to the region's coffers.
Where does the money go? If you really want to know, get involved in your organization and find out for yourself - and others - exactly what is happening to the money. If it is a non-profit, it has to have some degree of transparency. And, most likely, they would welcome the help -- finding responsible people to help manage a non-profit is an ongoing concern of many organizations.
