It's only my second year boarding, but my three days there improved me dramatically. I was there at Christmas time, and, although there were many people there, the slopes were never crowded. It was like it was my own private resort. In addition to a variety of courses of varying levels, the powder and off-piste stuff was great. I've never had so much fun.
In addition, the night skiing area covers a huge part of the resort, so you are not limited to one or two runs.
