Wow, a whole new Fantasyland, Avatar, new theater for Lion King, New Test Track, like them or not. Yea no new attractions going up anywhere, it's all money grabbing packages. What??
Disney isn't taking anything away from regular park guests and giving it to these Premium package users. For example they didn't shut down the Monorails at night and now just offering them to package users only. This is another hard ticket event, though smaller in scale, like Christmas, Halloween and even dessert parties. If you think these are pricey then don't attend, but you aren't getting shorted when regular hours are over. I'm not sure what the foreboding is about more of these. They rope off a section and the rest of the park goes about its business.
Disney never said the parks had a curfew or quiet time, if you get a room too close to this that keeps you up, ask to be moved.
