Ive read recently that you still need to line up about 45 mins before the show in order to get a seat in the reserved section, as they open up the reserved section to the general public 30 mins before show time. If this is true, you don't gain much time by doing the package. I would eat where you want and then line up about an hour before the show.
FWIW - we usually opt for the standing room only section. We are two adults with no kids so it might be easier for us, but we walk in about 20 mins before show time, sit on the step until the show starts, stand for the 20 minute show, and slowly walk towards the exit as the show is wrapping up. Then we are able to make a quick exit and aren't stuck in a row of bleachers. F! is just ok to me so we are fine with doing it this way.
