I'm a local!
There is plenty to do in Vancouver! Now it's just a matter of WHAT to do.
A lot of good stuff has already been mentioned so I will mention other items.
With the Olympics here, we have the Olympic torch, which is right next to the Vancouver Convention Center and the 8-bit orca whale. Walk along Coal Harbour and you hit Stanley Park (great place to walk, rollerblade, bike, stroll, crawl).
There's also Whistler if you want to go up a bit further! It's got it's own culture
Lynn Canyon is also a beautiful area, and don't forget the Capilano suspension bridge. Deep Cove should also be considered in this area as a nice little town away from towns by the Burrard Inlet.
Also consider kayaking/canoeing and checking out various beaches and parks!
Lots more to consider but I will let others chime in
