I probably would not buy this ahead in future as there were no queues and as I had already bought the ticket we felt we should visit it but could not see much on the day as smoke from the fires several 100 miles away overshadowed Vancouver most of August.
Great view of city. The best part is you can use same ticket to go during the daylight hours and then go back at night to see the sunset and city lights. There are interesting plaques around the viewing area so that you know what you are seeing.
Lookout is not as tall and big as CN Tower in Toronto but still good place to view city from high up. I liked idea of buying ticket allows me to go up all day because wanted to view city day and night time.
There were enough information displays inside to give interesting history of city.
Lower level of tower has many shops and if that's not enough the location is close to many other site seeing places like Canada place, Stanley Park and Gasstown. I did not deal with lineups but as any other tourist location there is always a chance you might have to wait for a bit before going up.
The view is exceptional and the great thing is that the ticket is valid all day- so you can go in the morning and then come back in the evening to watch the breathtaking sunset! Highly recommend as the last thing to do before leaving Vancouver.
