You are not flying into Seattle are you? If you are flying in and out of Vancouver also consider Vancouver Island and the lovely Gulf Islands. If ou want to see Killer Whales the Gulf Island would be a great place to whale watch from. Seeing bear can involve a lot of luck. One of the best places in the world to see Orcas is Telegraph Cove. They have bear tours out of Campbell River both on Vancouver Island. This may be much farther than you want to drive and you start getting pretty remote, but a couple of suggestions. Not sure what kind of vacation you are looking for.
Sorry! Thanks for letting me know
