I went last year, and it was a lot of fun, and the reviews were well organized, and they had some great reviewers. The portfolio walk was a bit disorganized, but there were a few reviewers who I was not scheduled to see who came by to look at my work. I appreciated that, but not all the reviewers showed up for it.
So, if you can get in for the reviews or any of the shows and workshops, I would say it's worth the effort.
