Take the train
Zero stress · Cheap · Unlocks less
VIA Rail runs 34 departures a week from Montréal's Gare Centrale to Gare du Palais, a beautiful old station sitting right below the cliffs of the Old City — a short (if steep) walk or a five-minute cab from most Old Québec hotels. Average run is 3h26 across 270 km. Reclining seats, WiFi, power at every seat, a café trolley, and kids can get up and walk around. No rental counter at the end of a flight day.
The family details worth knowing. VIA's Economy includes a centre table when you book for three or four passengers — a family of four gets a facing table, not four seats in a row. And children ride at half the adult fare, which VIA doesn't advertise loudly and which makes this considerably cheaper than most families assume.
Be clear-eyed about one thing: this is not a scenic route. It runs inland via Drummondville through farmland and small towns, and you only really meet the St. Lawrence on the final approach. Pleasant and easy, not spectacular. Don't book it for the views.

More freedom · More friction
Roughly three hours on Autoroute 20 or 40 — a straightforward divided highway, not a mountain road. Your U.S. licence is valid. Pick up and drop at Montréal, so no one-way drop fee. In fall the drive itself runs through good colour country, which the train largely misses. And critically, a car is the only way to reach Île d'Orléans, which is one of the best things in this guide.
What actually trips people up: road signs in Québec are in French only — no English translation, unlike much of Canada. Speeds and distances are in kilometres. It's genuinely manageable (arrêt means stop, and the signs are the same shapes you already know), but if that sounds like more than you want at the end of a long travel day with tired kids, take the train and don't feel bad about it.
