We went during the Christmas / New Year break; this was our first "big" mountain. The village is based at the top of the mountain, which was pretty unique. It made the ski-in/out functionality of the hotels great. You leave your room and get in a run immediately, without a lift line. But those lift lines were crazy. You could wait as long as 20 minutes. Advice - always go in the singles line!
There's a variety (and decent quantity) of trails. The bad thing is that there were far too many beginners or families; the greens were packed, and you had to constantly be on the lookout falling children, or groups who would congregate in the middle of the trails. The more advanced terrain was much more open.
However, they have Silver Creek, which was nearly empty (until about an hour or so after the main resort closed for the day) (but even then, it wasn't crowded). We didn't ski there during the day, but if you're really fed up with the crowds at the main mountain, this would be a great alternative. This is where the night skiing happens, and it's definitely great for that.
We didn't do anything at night except sleep, so I can't comment on that. Also, the terrain park(s?) all seemed to be over at Silver Creek. What I saw seemed okay, but nothing special. It was early season, so I'm not sure if they had everything set up yet or not.
If we go back, we'll spend more time on the blues and blacks, and over at Silver Creek. Considering how non-traditional its location is, it's a great place to ski.
