It can get a bit tiresome, there are always the inevitable complaints about some aspect - even cost (even though sometimes the event is actually subsidized (intentionally) by the organizers - and I've even had a chargeback filed because the payer (not an official Flyertalker but a friend of a FTer) forgot what the payment was for).

Another IBB that I frequent, many of the members actually travel together on cruises for vacation - this was the 5th year in a row that we've done that.
