Arriving by plane in Montreal, and want to avoid renting a car. I understand there's bus service from the airport to the Downtown area, where our hotel (Le Westin) is around the area we want to explore for a day or so. It looks like in Montreal, the metro gets you around fairly well.
Then we want to head to Quebec City, by train (for speed) or bus, and it looks like that's out of Gare Centrale.
Then, around Quebec City, we want to sight-see mostly around the historic areas, and it looks like buses and good ol' ped transportation will do the trick.
Of course, then back to Montreal by train (or bus), then fly out the next day.
Does that sound about right? Any gotchas I should consider? I've read taxis are pricey out of the airport, so the bus is more recommended. Is that right?
