The only thing I did wrong last year was spend money on the After Effects courses. Total bust, boring teachers, poor presentation. Won't do that again.
Save your money. (It was my first NAB).
I switched to another course line on the last day of classes and sat in Jeffry Fishers' audio for video class (using Vegas). That one was excellent. Anything Douglas Spotted Eagle (aka Spot) does is guaranteed to be good too.
Count me in for a hotel room block. I'll wait until something is posted here.
