My family including my wife and 17 and 9 year old sons will be have about 5-6 days in Colorado next August. We were planning on spending time in Beaver Creek and we have recently heard about Glenwood Springs. We will be coming from Las Vegas and plan to fly into Denver. If it were you, would you drive from Las Vegas to Glenwood Springs to fly to Denver and then rent a car? How much time would you allocate between Beaver Creek and Glenwood Springs?
