Like Catpiano, I lived and grew up in Alberta. Used to go to Banff sooooooooooo damn much!
Wanted to come to Vancouver more! LOL.
Nothing really good to eat and shop in Banff other than the brunch buffet in the haunted Banff Springs hotel. 
If you like to enjoy the scenary, while at the above hotel, talk a trail walk on the right side of hotel. Go to the short cut of water fall on the left side of hotel. That's a short 1/2 day trip.
For Jasper, same, shoping is expensive, not much in town. However, you can take the gondola and there's a long long trail with stairs leading up to the top of mountain. You'll see lots of squarrels and mountain goats like right next to you! This is probably a 1 day trip including driving.
Driving isn't so bad on highways. However, us Van ppl are not used to the snow and road conditions. I'd say be careful and anticipate quite a bit of curvy roads. Don't slam on the break when hit ice patches. You certainly don't need to chain your wheels though. 
Too bad you are not going with us which is this weekend. You can stay at one of our 3 houses there for free!
OH Calgary food is not great. I like Alberta steaks though... |
