The easiest way to answer this is...
just follow the headlights until the morning light. Then, just follow the 98 of your nearest and dearest friends.
By this time, the route up the chute is pretty much beaten in. I would not be surprised if it were beaten in to the point of steps...which makes things really easy.
Your concern should be focused on the way down. You have to make the decision to glissade or not to glissade. Then there is walk from Trailside Meadow to Mirror Lake, where most seem to lose the trail...myself included more times than not.
