My W wouldn't go to RetroV but I know a few people who have and they all give it rave reviews. It's not a miracle cure, however, and at least 2 of the people who went basically continued on their prior course. I have heard, however, that it's deep and meaningful and can turn around a really really difficult situation.

It is Christian-sponsored, but from what I've heard the religious side is unobtrusive. I'm a UU so I definitely didn't want some dogma-laden weekend but from the research I've done it's not an issue and I would have gone.
