I would still recommend Stanley park for a number of reasons, In terms of photography there are endless things from herrons (they're nesting area is about 5 blocks from where I live| lost lagoon has lots of birds, raccoons and skunks If you take the trails the scenery would be like being in a forest huge trees, wildlife , etc. Of course if you go to a place in the park like prospect point you will have wonderful views, if you google prospect point Stanley park pics you will see what I mean
The other reason I suggest the park is its proximity to the the west end, ( lots of ethnic foods, gay area, little sisters bookstore gay book store, restaurants Gay bars and where I live lol) Coal harbour, Yale town (trendy areas , along water good food and walking, Sea wall )
Also from the sea wall its good to take the little ferry to Granville island. I often do that with my out of town company.
I've lived in Vancouver for over 20 years so feel free to ask me what you may be interested in :)
