Like most towers, this is a great overlook of the city. We were pleasantly surprised at the lack of visitors in the tower. We came on a weekday just after opening, and I don't believe there were more than 20 people in the place.
There are 360° views and places to listen to commentary about what you're seeing as well as placards describing things in the background. We spent around half an hour looking at all the destinations and taking lots of pictures.
We can recommend a stop here for a beautiful view of Vancouver.
