McGill or Montreal U? My step-grandson graduated from McGill.
Tremblant - damn near the coldest place on earth!! But the skiing is great. There are 4 faces to the mountain. And it can be very crowded on weekends. February sees the American Presidents week, the college and university "reading weeks" and possibly the first of 2 public school weeks. Those can be more in March too. Tremblant is the biggest in the Canadian East. Mt Ste Anne is just behind.
Advice - if your son didn't get to the MEC event for cheap tickets for students, then hit Costco on your way up. There's one in St. Jerome, just at the 641, 15 interchange. Dress for really cold weather.
SkiBam, the Ski Diva and myself....early February last year. Taken on "the Edge". The way to avoid the crowd is to ski with a local. We know where and when to be to avoid them. Suggestion - lunch at the Windigo cafe in the bottom of the Fairmont. Much more civilized than the mountain top cafeteria.
If you're staying overnight, check the Air BnB places. Much cheaper than the resort or maybe you have Marriott, Westin or Fairmont points. Also in the village of St. Jovite there is a Comfort Inn.
On your way up the autoroute you will see - St. Saveur, Avila, Olympia, Gabriel and Mont Blanc. All much smaller is vertical, but fun places for families.
In the townships - Mt Sutton, Owl's Head and Jay are my favs.
Heading up today for the CSIA convention.....like the PSIA event next weekend.
