So I'll be visiting Montreal in a couple of weeks. I've been told that Quebec City might also be worth a visit. I'd make it a day trip.
Considering that I don't want to rent a car, what do you think would be best to do Montreal-Quebec and back in one day? I've looked at fares by plane for Air Canada but they're not exactly cheap (about CAD$600 per person, and we're 2). The train would be much cheaper (about $100 per person) but takes 3 hours each way.
Is there any option I'm missing? Maybe a LCC that I don't know of? Amadeus doesn't show anything else, but who knows - I thought it's better to ask than being sorry afterwards.
