We went mid-August and got the little drawstring bags, too.
It was quite crowded and some of the other attendees were quite rude, but it was an OK experience. We just bought our DVC in May so we thought it was worth checking out.
DH won a resort photo session and PhotoPass CD, so that saved us $125. That in itself made it worth going!
The lines for snacks and drinks were insane so we didn't sample any of that.
