I know the question "Is it worth it" is very subjective but my question is what, exactly, do you get for the money?

Things I've seen and read about that you get:
candy
special fireworks
special parade

Are there special things on the rides that will be open?
Do you get free, unlimited pop, water, ice cream bars and popcorn like at other ticked events?
Any AP discounts?

Just wondering what I may be missing before I decide to shell out that kind of money. BTW, it'll only be adults, no kids, so maybe that makes a difference?
