There were massive problems with the promised accommodations, that in many cases were prepaid but then not available when the participants showed up. And I heard of one couple who were actually jailed for alleged smuggling of artifacts but they were released after a few days.

I also heard that the lectures and bead sale were outstanding.

So the people involved need to fill in more details, but I know for sure that some of them are still angry and do not want to talk about what happened to them and what it cost to straighten out the mess.
