This was my third trip to vancouver, but is always a pleasure to return to. Have a look at some of my other reviews for more details of recommended things to do and photos. E.g. Canada Place, bike ride around the sea wall of Stanley Park, Gas town, Chinatown, sea bus.
The Sky Train from the airport is fantastic! $8 each takes you from just outside the airport main doors through the city. One stop is at the Sea bus station near Canada Place if you're heading to North Shore as we were. On the way back it only costs $3 each for 2 zones! Try to include a visit to Grouse Mountain and Capilano Suspension Bridge (or Lynn Canyon).
