Rent a car in Vancouver, rent a room with kitchen in Whistler (it is low season so good rates) i.e. Blackcomb a little outside of the hubbub and go hiking from there. Just make a stop in the village for a cold one on the way back.
I can recommend Brandywine Meadows/Glacier (outside of the more popular Garibaldi park with Black Tusk:-) ) nice and quiet. Toward Pemberton I do like Joffre Lakes and of course a little bit more popular the whole Garibaldi provincial park. I have a few out of the beaten tracks hikes but require a 4x4 and knowing well the places. It is worth taking 3 or 4 days there.
Well that should pretty much take care of the 11 days before you even realize it.
ps: in Vancouver hike Mount Seymour nice easy and beautiful views.
