Not been in years past, but am booked for this one.

I imagine it will follow the formula of most of these events (TechEd, PDC etc) albeit on a smaller (more intimate?) scale - a good chance to network and get re-enthused, especially about future stuff away from the dreary day job, but probably not great value for money if your main reason for attending is training (the conference itself is reasonably priced but the hotel, even discounted, is extortionate).
