Whistler December 2008

I have the task of booking my bosses' family ski holiday and they've decided they want to go to Whistler. Can anyone recommend a good condo, to accommodate 5 people in 3 separate sleeping areas (loft OK but not sofa-bed in lounge), within easy walking distance of lifts and nightlife? And preferably under 600 dollars a night - I know, a big ask, but any recommendations would be much appreciated.
