Might be too late to get this info to you, but I'd recommend Stanley Park (nice for a walk and view of the city), Grouse Mountain (for hiking and maybe mountain biking, weather-permitting), and an overnight or longer trip to Whistler prior to the Winter Olympics this February. Lots of places to shop; Granville Island offers a good mix of local crafts and cuisine. This article is a little summer-centric, but could toss up some decent outdoor ideas: http://away.com/features/family-vacations/canada/vancouver-390342.html
