This is probably to late for you but maybe it'll help some others looking for accomadation etc. in YVR and actually all over.
This group of pilots setup a
Vacation Rental/Exchange Forum which is all free anyway one of the listing on it is a friend of mine whose an AC pilot.
Once you enter the Forum in the Canada section you'll see a post for downtown Vancouver with lots of info on his 2 bdrm apartment. I've stayed there many times and it's a great place and location and he usually gives some great deals.
This forum also has some pretty good aircrew tips on where to eat etc.
Hope this helps and have a great time in a wonderful city.
