I planning on heading "up north" for a ski trip in two weeks, and I'd like to know from the people skiing there if my money would be better spent somwhere else, say Killington. With Killington blowing and no mention of any blowing at Whiteface, I'm pretty worried about the conditions. Although I've been to Tremblant, I'd hate for my first Big mountain experience to suck. Let me know what you think.

If its a choice between the two, whiteface. Its going to be cold for at least a week.
Now if you are open to ideas I would say go up to Jay Peak or Stowe. Both of those areas will have more snow and natural terrain.
Killington will have more snow but late in the year the only option you have for expert trails are bump runs.
