With only one week and an "iffy" crew, you might be better off using your car and the ferry system to explore B.C. waters. Anacortes to Victoria, Gulf Island ferry routes from Sidney to Saltspring or others. Back on Vancouver Island, drive up to Courtney/Comox thence across to Powell River and down the Sunshine Coast to Vancouver. You''ll get some "sea/see-time" and lots of time to explore. And your US$ vs CA$ exchange rate is very much in your favour. Good Luck. Cheers, Richard.
