Never skied there but have visited on a day trip from Banff (amazing journey - a must do).
Nice Town, slopes looked nice but I think you will be bored for 2 weeks and it isn't exactly adjacent to any other ski areas, in fact slopes aren't exactly adjacent to Jasper (but neither are Banff's) nearest resort is Lake Louise and that is about 3 hours by car.
In January I would recommend taking plenty of thermal wear it is unlikely to get above sub zero and can be minus 20deg.
