Still lazy and tired (this vacation was to slide on snow and rest) but I'll add a note on logistics since I usually find logistics-type stuff the most helpful for ski trip reports.
@Ski Sine Fine you might be interested.
Flew nonstop from Montreal to Calgary, checked a ski bag for a very reasonable $35 CAD on Air Canada. Calgary airport is super easy for car rentals and ground transport. On the ground side, the airport is split between the international and domestic terminals. They are connected via a long hallway.
Both bus transit options to Banff, the Banff Airporter and Brewster Express, have a counter on the domestic arrivals side of things where you check in prior to your scheduled trip. I'm not sure if they have anything in the international arrivals terminal. I did end up taking the Banff Airporter but honestly between the two, both are perfectly fine. I read the signage at the Brewster Express counter and it said their buses have wifi; Banff Airporter does not. Trip took about 2 hours with a stop in Canmore.
The bus dropped me off right at my lodging so that was easy.
The ski bus from Banff to the resort is also quite straight forward. The town of Banff is small and from what I can tell, all of the major hotels/accommodation is just a short walk from a ski bus stop. They are marked with SkiBig3 sign posts. Everyone is required to take a seat on the bus; if the bus runs out of seats, they will call another one. So, no need to worry about not being able to get a ride to the resorts. Same on the way back -- if one bus fills up, they will start up another bus.
A note on car rentals:
Unlike the Denver airport, where the rental car counters are a long bus shuttle away, the car rental counters at Calgary are an easy crosswalk away.
I skied on Friday with a lovely woman who posts on SkiTalk who is local to Calgary; Sunshine Village is her home hill. She said that it is very uncommon to be able to rent cars with real winter tires; all season tires are much more common. Highway 1 between Calgary and Banff is straight and does not include any high-speed sharply curvy turns (unlike, say, I-70 in Colorado) and according to my ski friend, people are generally OK with slowing speeds down when conditions are bad and it's fine to camp out in the right lane going at a comfortable speed in all seasons. My only previous experience with Banff has been in the spring where no snow tires were remotely necessary, but I think I'd be way more comfortable driving from Calgary airport to Banff on all seasons than I am driving from Denver airport to any of the resorts on I-70, which I've done before.
Since Dr Pugs and I also plan to do a trip to Revelstoke and Banff mid-winter, I asked my ski friend if we should buy chains for driving through Rogers Pass. She said no - if there was any avalanche risk, the pass would just be closed and chains would not make a difference. (FYI to
@elemmac again! Ymmv of course.)
Aside from being freaking gorgeous, having a huge variety of terrain and being affordable to Americans thanks to the exchange rates, Banff is one of my favorite places to go for a ski trip because it's so darn easy to get to from northern Vermont -- as long as the border's open. Much easier than, say, Reno, that's for sure, and the airport experience is massively better than Denver, too. Last April, it was also pretty easy to get to from San Francisco (direct flight) and my mom had a pretty easy time flying home to Boston via Toronto airport.
@ski diva I really recommend revisiting your Banff Diva West idea sometime! Maybe a spring skiing visit so the group can avoid the really cold temps? Tomorrow is going to start at -10 degrees Fahrenheit
