Post production world is the thing I’ve found the most valuable. I’m in a similar situation, in-house, soup to nuts production. I’ve been to PPW for 2 years in a row and came back energized, more informed and inspired.
PPW is Ala carte. You go to whatever session whenever you want. There was usually always 1 or 2 sessions I wanted to attend. The value ($800 in 2012) is well worth what you would normally pay for training.
I’d spend everyday I can at PPW and go to the show floor for one full day. Show floor is cool, but unless you are actively trying to purchase new equipment, I don’t find a ton of value spending much time there. Obviously, this is my opinion and others would probably disagree.
