Really want to take the Canadian in the next year, probably westbound. Most interested in travelling low season due to cost (will go Sleeper Class) and getting full access to the Park car. My question: is it better to travel in the fall (after Oct. 31) or in the spring (before April 22)? My sense is fall would be the slightly better bet because weather might be more cooperative. And is westbound the preferred direction? I prefer the idea of building to the highlight of the trip, but if the better views come via the eastbound direction I'd consider it. Sure, I would love to go in summer with the most daylight but not eager to pay the fares in high season. I appreciate all viewpoints.
