FWIW, I was noodling around on the SouthwestAir website pricing their early season 7-day ski vacation packages.  I priced one for Tahoe during the week we went to Whistler last year (Dec 7-14 this year), staying at one of the big casinos at the South end and renting a 4X4 to get around.

It would cost us $2275.00 total for four people for rt air, lodging, breakfast, taxes and the 4X4.  That's only about $570.00 pp.  A 6-day BigSix ticket adds about $275.00.

That's about $845.00 pp total.  Not a bad deal, if there's early season snow, always a bad bet in Tahoe, even in an El Nino year.
