Actually, the seats are somewhat off to the side, so likely worse than what you could get on your own.
For me, the advantage of FDP is that I don't have to wonder if I should head over now, or if I have a bit more time. Often, the theater fills up more slowly than I think it will, but there's always that mental stress of "will I make it" when I don't have the package.
That said, I generally skip it unless I'm there during a pretty busy time.
