Hi Misty,
The schedule for Fantasmic is embedded in the
main calendar for Disney's Hollywood Studios. To see the Fantasmic times, just like inside any of the individual boxes in the calendar grid. For example, you can see the schedule for
November 9, 2012.
You've chose to visit during a fairly low crowd week (YAY!). At the time of your trip, guests will typically begin lining up for a seat at Fantasmic about 45-60 minutes prior to the show. With the Fantasmic dinner package, you have to arrive at the theater 30 minutes in advance. So at best, you'd be saving yourself about half an hour of wait time if you got the package. You could use that time to grab a hot dog from a nearby stand and eat while you wait.
There are times when I would tell you to absolutely get the Fantasmic package, but personally, I don't think it's big necessity in early November.
Good luck with your planning. Please let us know if you have additional questions.
