We're going skiing at Xmas for the first time in over 20 years (and teenage children have never skiied). We're trying not to buy too much stuff as we're not sure how much we're going to enjoy it and if we'll be going again or not. Do we need sunglasses and goggles or can we just make do with one of them - and if so, which? Feel some tips from experienced skiiers would be really helpful! We're going to Sainte Foy and driving down so the whole thing's a bit of an experiment to be honest....
