I thought I would respond to the above comments with my own two cents. I've attended two fests (not this year.) I think much of what has been written above is true, even by those who seem to be disagreeing with each other. It is true that the stars sell their items, make money and have their expenses paid for to boot. Not a bad deal at all. So there is truth that the appearances, as someone said above, are not 100% "noble" and contain some self interest. It's not all out of the goodenss of their hearts. And as someone else said, we poor or middle class fans, have to pay a ton of money to get there, hotel, dvd's and lots of monetary support over the years. All true.
But on the other hand, my own experience has been that the DS actors are some of the nicest, most gracious and personable people you can ever meet. That's not something that can be faked. If they came across as only snobs who were doing it for the money, that would be one thing. But they don't. So I really think they're great people. If they were not making money would they still come because they just love us fans so much? I don't know, but the fests are great times. We should enjoy them for what they are.
