We are a family of 6 adults planning a ski vacation in Aspen and Vail. We always stay somewhere for a few days first to acclimatise to the altitude and get over jetlag before we ski, and this year we plan to book at the Hot Springs Lodge for 4n over new year. Can you recommend activities as well as the pool at that time of the year and also suggestions for NYE. We will have a car. Any advice appreciated.
