Myself, I like driving places, on my own schedule. If I had the dough, my first choice would be a driving tour. I'd be picking my own routes, stops, and timetable. I wouldn't even have to go far. BC is a beautiful place, and I think you said you hadn't seen a lot of it. Or maybe I'd rent a wilderness cabin at a fishing resort, or something like that. You like fishing?

Of course, driving your own car will probably cost you a a fair bit more than a train or bus ride.
