I attended one last year and found it to be excellent.
You get given a variety of lectures and talks from a wide range of speakers on various but relevant subjects.
You get the opportunity to do a wee bit of teamwork and discuss things in a helpful and open manner.
There's no talking down to each other, theres no standing up and presenting by yourself to a room full of instructors, its all really informal and in a small group of about 6 or 7.
I'd highly reccomend it.
