For the cost, there's not much reason for many of us to take notice since most of us go so often anyway and know how to manage with crowds and such. It's really meant more for minor celebrities or just well off people who want to be treated like royalty.
I think I've seen it be used a couple of times. You basically get your own SDC handler to let you into all the rides through the exits. It causes all kinds of complaints though...

It might make the Christmas experience more enjoyable... if you can ignore the glares from the people you bump in the station. I think it makes more sense to save the $200, get their early, get your ride on Time Traveler, and enjoy the rest of the park at your leisure. Sure, it can be crowded at points, but at Christmas time you can focus on the lights if nothing else.
