I think the "problem" here (if there really is one) is down to cultural differences between the format often used in Ireland (which I find to be somewhat elitist and often alienating), and that used in the US/Canada.

The NA side of the pond, we tend to think things should be done democratically, ie, let the students choose the teacher. It is (at least at most schools I'm aware of) done the opposite way in Ireland, where the teachers/organizers place the students.

I agree that there should be a disclaimer given at NA schools like GR, where the classes will be structured and students assigned "Irish style". That way, if someone doesn't like their placement, then the refund option wouldn't seem the least bit rude, as it would have been spelled out just like that.

I honestly don't know what the "best case scenario" would be for NA festival workshops like GR, which does bring in some very fine "master players" to teach, but not very advanced players as students.

But then again, I can't imagine anyone being unhappy that they would get a week's tuition with Kevin Burke, either.
