We've stayed at the Grand Canadian in Canmore twice; once in summer and once in winter. Both times were absolutely wonderful family vacations.
The only negative thing I can say about the resort is that it doesn't have an onsite restaurant. This is really only a minor concern though because there are many wonderful restaurants and little shops just a few minutes drive away. The location is quiet and secluded and absolutely perfect for relaxing after a busy day skiing, hiking or taking in all the fun things to do in the area. We've stayed in a two-bedroom unit both times and found them to be clean, comfortable and very nicely appointed with a full kitchen, living area and cosy gas fireplace, perfect for warming up after a day on the slopes. The kids enjoyed the games room and the heated outdoor pool (even in the snow!) and we enjoyed the outdoor hot tub. I would recommend this resort to anyone who wanted a peaceful, very comfortable place to unwind after a busy day in the mountains.
