Six Flags Premium Pass. What's the Benefit?

Okay, I've looked through their website, and their FAQ's to find out what's so premium about the Premium Pass, and couldn't comre up with an answer. Anyone on here, get the premium pass, that might be able to shed some light on this matter.

The best I see is the coupon book, as an added benefit.

Not sure what it is this year or how it varies by park, but in the past the premium pass gave you free parking, food discounts (like 25%), free tube rentals, Flash Pass discounts and stuff like that.

Yeah, I remember that from being a previous Premium Pass holder myself, but if it doesn't include parking this year, then why bother. Just take it cheaper park only pass.

For Great Adventure, you used to need a Premium Pass to get into season passholder events like Coasters After Dark. It's not an issue anymore since it looks like the new management cut back those events and they aren't happening this year.
