We have done both (train to montreal and drive to quebec) and I would NEVER take the train again. We were waiting around at the border for HOURS and HOURS while they checked everyone's passports. If there is someone on the train whose paperwork is not in order, it holds up the whole train while they check it out. I think it took us fourteen hours from NY.
The car ride from montreal to quebec is easy and fun (especially if you have a GPS which makes it a breeze).
For about 20 years we drove from Fairfield County Connecticut to Quebec City every President's week to ski with our kids at Mt. Ste. Anne which is 30 minutes from Quebec City....sometimes we drove via Montreal if we were going to ski a couple of days in the Laurentians....The roads are fine...but if you go in winter be sure to have good tires and AWD....they get so much more snow than we do in the NYC area.....Quebec is not a difficult city to drive in.....I just love both cities, but especially Quebec.
They must have changed affiliation, previously it was an RCI resort.
I was at Club Vacances Toutes Saisons in July 07 visiting Quebec City, and tried to check out the surrounding resorts. It is possibly 1/2 mile from the base of Mont St Anne.
Just drove around, didn't see the interiors. I thought it was one to take a chance on if there again.
When are you going, sounds like pile in a lot of skiers.
