Jim,
I live in the Vancouver area and would be most pleased to get together next summer.
I have played at Sagebrush for the last two years and absolutely love the place, as does everyone else I have played with up there. It is a wonderful experience. From downtown Vancouver, you are looking at about 3.5 hours. From my house in White Rock, it is about 2.5 hours plus a bit, depending on who is driving.
Regarding Whistler, from downtown you can be there in about 1.5 hours or a bit more if traffic is bad. I prefer the original Whistler Golf Club over Nicklaus North and the Chateau course. Cheaper too. It is fairly flat and runs along the valley between the mountains. An easy walk and still pictureque. Undulating typical Palmer/Seay greens, good variety of holes. Fairly wide open. Furry Creek is on the way to Whistler from Vancouver and I agree with Dale and the others that you do not want to play it. Far too goofy. I could never understand why Sean Leary liked it so much, but that's Sean for ya!
Dale is correct in that Big Sky in Pemberton (about 25 minutes beyond Whistler) is very good. A Tom McBroom design.
Feel free to contact me re Vancouver golf as well. I will add that Point Grey is a better course than Marine, although some say I am biased. For private courses in Vancouver, the ranking is Capilano, Shaughnessy, Vancouver GC, Point Grey, Marine Drive, Seymour in North Van (semi-private, open to public only Mondays and Fridays).
