I would love to go but cannot afford it. You want a really good deal contact Chalet's Mont Ste Anne (the brownish townhouses at the bottom of the hill) they have a couple of times a year that skiing is included in the rental of the chalet. Depending on how many people you get in the chalet it could cost about $300 per person, or less, for 4 days of skiing including your accommodations. And the best you ski right to your door. I know they do it in February sometime. The hill is never busy either. I have NEVER stood in line for any lift at that hill.
As for black diamonds, I am a chicken, I stick with the green and a few of the blues. I am not a very good skier but just like to go and have fun. I like skiing on the other side (I think it is the north side) the runs are shorter and are pretty easy. Still have to come back down the other side though at the end of the day. I miss it I havnt been in about 4 years now.
We used to eat breakfast at the top of gondola in the mornings was pretty cool to do that first thing in the morning.
