On the plus side, great off piste experience, wonderful long runs, the linkage (gondola) between Whistler and Blackcomb was fast and efficient even if there was a line it moved fast. The upper alpine runs were different exciting and fun. The upscale on mountain dining experience were very nice and worth doing. They take reservations and walk-ins only had a short wait for us, but we lunch late.
On the negative side, Very crowded even on week days (this could have been the fact that the only really big snowfall was late in the season. When the upper alpine runs are closed the crowds at mid mountain were miserable ((ie 45 minute lift lines and big crowds on the slopes.
