Avoiding lines: Do the Fresh Tracks breakfast (skip breakfast and just wait for them to open the runs for an even better start). Eat lunch at 11, then head out when everyone else is heading in. I did this last weekend and lift lines were literally half at 12:30 what they were at 10. Or, make a reservation at Christina's or Steeps for lunch to avoid the lodge mobs. I find lines to be not as bad at Garbanzo and Big Red (in the afternoon at least--maybe not Big Red when everyone is still uploading) when they are bad everywhere else.
On Wednesday of last week the weekend forecast said sunny and cold. I skied all weekend in warmish temps and heavy snow (rain at the bottom). So don't put too much stock in the forecast. On the bright side, if it hasn't snowed in a few days locals might stay home, and the alpine will be open with good visibility. I never even ventured up high last weekend because it was dumping and I like to see where I'm going.
The Village is crazy, too, Unless you're cooking in, if you don't want to wait for dinner, you might think about making some reservations, or eating early.
