I just don't think 30 minutes, regardless of the park, is that great of a benefit. Given the time it takes for stuff, you're really only going to be able to get one, maybe two rides in before regular opening, if they aren't the headliner rides. Waiting in line is going to quickly going to eat up that 30 minutes. If you have one specific ride you must do, then I guess this gives you a chance to avoid a bit of crowd. But that's still not much of a perk anymore for staying onsite. And honestly, I can't think of many other on-site perks anymore. EMH really was the selling factor for a lot of people I know.
