Just starting out planning a family vacation of two weeks for my family including my husband and twin 22 year old sons to take place in early January. We are a family of two advanced skiers and one snowboarder with me who is going along for this portion of the trip to be accomodating but will maybe go off solo or go cross-country sking. So I need advice about Chamonix as a optimal destination for a 4 day portion of our trip. We would like to combine this trip to possibly include Rome and London. My one son has his heart set on this one area but I would love some feedback about this being the best choice. I am a bit concerned about costs but also whether this is the best choice for our once in a lifetime (paying for my son's journey) as our family ski experience in Europe. I am somewhat overwhelmed planning this type of trips from Chicago so would love any and all advice about our choice about ski slope considerations, accomodations, feasibility of travel, car, food etc.
