I will be coming from Denver Airport to Vail December 16th. I was wondering if anyone could tell me how long a drive that will be that time of year as I have come many times but not in winter. I know in summer that traffic is very heavy coming out of Denver to Vail on a Friday night. Also are the roads kept clear if it is snowing? Thank you for any information you can give me as I am trying to make some reservations once I arrive and don't want to cut my reservations to short by not having a time line.
