Your visit to Whistler is because of the Whistler Blackcomb. You are very likely to get on the Peak 2 Peak Gondola there. It's one of the most famous attractions in Whistler. When I was there, the weather was really nice and I was early enough so the line to get on the gondola was not awful at all. The view from the gondola ride was amazing and the ride covered a pretty good distance too. It's really cool to see so beautiful scenic mountains in Whistler. The gondola also has the glass bottom kind, but the lines can be long.
