The Sony training room, which is behind the booth in the first hallway to the left (as you face the main entrance near the Sony booth). You need to sign up for the classes in advance.
It's real training. The SCVUG guys streamed it last year, I know it helped a lot of people get familiar with how to use various functions in the software. It's a slower class, due to the size, but it works pretty well, IMO.
See ya at the party!
