Obviously there are different levels of accommodation for different people:

From the Downtown Youth Hostel https://hihostels.ca to the Granville Island Hotel https://www.granvilleislandhotel.com/ likely there is something for you out there. 

AirBNB likely has something https://www.airbnb.ca/s/Vancouver--Canada  as will the more traditional Tourim Vancouver site.

I'm getting up really early, so likely you don't want to stay at my place.
